Dear all,
On Friday May 3 we will have an IIHE seminar from Dr. Cecile Caillol:
"Observation of the photon-induced production of tau leptons in pp
collisions at CMS and constraints on tau g-2"
at 14h30 in the Sacton seminar room (G.1.03)
Abstract and short bio are below; the event's agenda can be found here:

Abstract:
The photon-induced production of a pair of tau leptons had been observed
in proton-proton collisions with data collected in Run-2 by the CMS
detector at the CERN LHC. Signal events are identified thanks to their
low track multiplicity around the di-tau vertex. These events are used
to set constraints on the anomalous magnetic moment of the tau lepton,
significantly improving previous measurements from the LEP era
Bio:
Dr. Cecile Caillol did her PhD at the Universite Libre de Bruxelles
(Belgium) and graduated in 2016. She then joined the University of
Wisconsin-Madison until July 2021, when she became an LD staff
researcher at CERN. During her PhD and after, she worked on Higgs boson
decays to tau leptons, including the first observation of H->tautau
decays with 2016 data, and other Higgs boson measurements with tau
leptons. She also played a leading role in several exotic Higgs
searches. More recently, she has worked on the study of photon-induced
processes (this seminar), and the lepton-induced production of
leptoquarks. She is currently convener of one of the 3 search groups of
CMS (SUS ˜= supersymmetry, dark matter, exotic Higgs).

Dear all,
On Friday April 12 we will have an IIHE seminar from Dr. Elisa Wursten:
"Experiments at the antimatter factory of CERN"
at 14h30 in the Sacton seminar room (G.1.03)
Abstract and short bio are below; the event's agenda can be found here:
https://indico.iihe.ac.be/event/1920/
Kind regards,

Abstract:
The Standard Model of Particle Physics is an extremely powerful model,
but it is known to be incomplete. One of its issues is that it does not
provide an explanation for the striking imbalance of matter over
antimatter observed in our Universe. To better understand the properties
of antimatter, the Antiproton Decelerator was inaugurated at CERN in
2000, providing a facility for dedicated studies of low-energy
antiprotons and antihydrogen. Since then, an impressive amount of
progress has been made, ranging from the efficient production, trapping
and laser cooling of antihydrogen to extremely precise spectroscopic
measurements and studies of its gravitational behaviour.
In this seminar, I will give an overview of the experiments at the
antimatter factory of CERN, concisely summarizing their research
objectives, their measurements concepts and highlighting the most
important results and plans for the future.
Bio:
Dr. Elise Wursten did her PhD at KULeuven, contributing to the neutron
Electric Dipole Moment experiment (nEDM) at the Paul Scherrer Institute
in Switzerland, under supeervision of Prof. Nathal Severijns.
Interleaved with short periods as Visiting Scientist Fellow of the Max
Planck Society, she was from 2018-2020 a CERN Senior Research Fellow and
Visiting Scientist at the Ulmer Fundamental Symmetries Laboratory of
RIKEN, Japan, working at the Baryon Antibaryon Symmetry Experiment
(BASE) at the Antiproton Decelerator of CERN, Switzerland. Since 2021,
she is a Special Postdoctoral Researcher affiliated to the Ulmer
Fundamental Symmetries Laboratory of RIKEN, Japan, working again at the
BASE experiment at CERN.

Abstract:
LHAASO has started taking data in 2021 with its full array. With its
large field of view and good performance, it has collected a huge amount
of high quality data. In this of talk we will illustrate the LHAASO
instruments and its performances. Later we will go over major
achievements and breakthrough results. In the end, we will also give an
outlook at the evolution of the array and LHAASO synergies with future
instruments.
Bio:
Professor Della Volpe currently holds a position as a professor at the
University of Geneva, where he contributes significantly to the
astroparticle pillar of the department. Additionally, he is actively
engaged in medical physics through his leadership role in the POSICS
project, which aims to develop an innovative portable gamma/beta camera,
generously funded by the EU H2020 program.
His primary focus lies within the Cherenkov Telescope Array Observatory
(CTAO), with a particular emphasis on the Large Size Telescope (LST)
collaboration, where he holds the pivotal role of System Lead Engineer.
His significant contribution played a crucial role in the success of the
Critical Design Review (CDR) of the LST, a milestone achievement that
marked it as the first telescope to meet the stringent qualifications
for acceptance into the CTAO.
His engagement with LHAASO began in 2017 through a collaboration on the
WFCTA Camera, where his group supplied the technology for the focal
plane. This contribution was notably acknowledged by LHAASO,
particularly noteworthy as his group was the sole non-Chinese
participant in the experiment and a member of the Institutional Board,
underscoring the significance of their involvement.
From 2018 to 2023, Professor Della Volpe chaired the publication
committee of LHAASO and served as the main editor of the LHAASO science
book. He has also made significant contributions as a contributing
author to seminal papers published in prestigious journals such as
Nature and Science. His main activity is in CTAO, and in particular in
the Large Size telescope collaboration, where he is the System Lead
engineer.
In the end 2023, he left LHAASO to focus on new projects. He is one of
the PI of the QUASAR project, aimed at pushing the boundaries of
Intensity Interferometry to achieve micro arc-second resolution using
picosecond light detectors. Additionally, he is collaborating on the
French-Swiss initiative known as LACTEL, which seeks to implement a
pioneering concept of a water Cherenkov detector in Lake Geneva,
garnering significant interest from the scientific community, including
the South West Galactic Observatory (SWGO).

Dear all,
On Friday Mar 29 we will have an IIHE seminar from Prof. Charlotte Van
Hulse:
"Study of hadron structure in ultra-peripheral collisions at the LHC"
at 14h30 in the Sacton seminar room (G.1.03)
Abstract and short bio are below; the event's agenda can be found here:
https://indico.iihe.ac.be/event/1919/
(note that via the top-left you can link the seminar agendas into your
agenda, so you never miss one!)
Kind regards,
Steven.

Abstract:
The study of exclusive processes in lepton-hadron interactions and in
ultra-peripheral hadron-hadron collisions provides information on the
three-dimensional distribution of quarks and gluons as a function of
their longitudinal momentum and transverse position inside the hadron.
Here, the longitudinal direction corresponds to the direction of the
probe used to investigate the hadron. An introduction will be given as
to how exclusive processes in ultra-peripheral hadron-hadron collisions
provide access to the internal structure of the nucleon, and relevant
experimental results will be discussed. Where applicable, parallels with
measurements in lepton-hadron interactions will be highlighted.
Bio:
Charlotte Van Hulse is a professor at the University of Alcala in Spain.
She did her PhD at Ghent University, where she studied exclusive and
semi-inclusive QCD processes in lepton-hadron collisions at the HERMES
experiment, at DESY, Hamburg. Subsequently she studied hadron formation
in e+e- collisions, at the Belle experiment in Japan, and performed
studies for a fixed target at ALICE. Nowadays she focuses on QCD
(exclusive and semi-inclusive processes) at the LHCb experiment as well
as feasibility/R&D studies for the future electron-ion collider at BNL, USA.

Dear all,
On Thursday Mar 7 we will have an IIHE seminar from Dr. Richard Ruiz:
"Vector Boson Scattering: Status and Prospects for the Large Hadron
Collider and Beyond"
at 15h00 in the Sacton seminar room (G.1.03)
Note the *unusual day and time* to accommodate the speaker's travel
constraints.
Abstract and short bio are below; the event's agenda can be found here:

Abstract:
The scattering of electroweak bosons at TeV-scale super colliders is a
powerful mechanism that probes spin and charge configurations
inaccessible to quark and gluon scattering. Electroweak vector boson
scattering (VBS) processes therefore give unique insights into the
Standard Model's gauge and Higgs sectors, as well as into models of new
physics. In this talk, we review experimental results and ongoing
theoretical developments of VBS at the Large Hadron Collider, its high
luminosity upgrade, and its potential successors.
Short Bio:
Richard Ruiz is a specialist in collider physics, and particularly
searches for violations of lepton symmetries using electroweak boson
scattering as a probe of new physics at the Large Hadron Collider.
After earning his PhD at the University of Pittsburgh in 2015 on the
topic "hadron collider tests of neutrino mass models", Richard moved to
Durham University's Institute for Particle Physics Phenomenology in the
UK. In 2018, he moved to the Universite Catholique de Louvain's Center
for Cosmology and Particle Physics Phenomenology and finally joined the
Institute for Nuclear Physics Polish Academy of Science (IFJ PAN) in
Krakow, in 2020. He is credited in his habilitation with "influential
theoretical contributions to understanding and using vector boson
scattering as a probe of new physics at the LHC, its high-luminosity
upgrade, and future high-energy collider experiments," which is the
topic of the talk.
Despite being a theorist investigating fundamental aspects of collider
theory, Richard is heavily involved in experimental activities at CERN
due to his work on developing user-friendly simulation tools.

Abstract:
SND@LHC is a compact and stand-alone experiment to perform measurements
with neutrinos produced at the LHC in a hitherto unexplored
pseudo-rapidity region of 7.2 < 𝜂 < 8.4, complementary to all the other
experiments at the LHC. The experiment is located 480 m downstream of
IP1 and the detector is composed of a hybrid system based on an 800 kg
target mass of tungsten plates, interleaved with emulsion and electronic
trackers, followed downstream by a calorimeter and a muon system. The
configuration allows efficiently distinguishing between all three
neutrino flavours, opening a unique opportunity to probe physics of
heavy flavour production at the LHC in the region that is not accessible
to ATLAS, CMS and LHCb. This region is of particular interest for future
circular colliders and for predictions of very high-energy atmospheric
neutrinos. The detector concept is also well suited to searching for
Feebly Interacting Particles via signatures of scattering in the
detector target. The first phase aims at operating the detector
throughout LHC Run 3. The experiment has taken data since 2022 and has
recently reported the first observation of collider neutrinos. We shall
review the first experimental results and the plans for the upgrade to
operate at the high-luminosity LHC. A new era of collider neutrino
physics has just started.
Short Bio:
Giovanni De Lellis was born in Naples, Italy, in 1973. He graduated in
Physics summa cum laude in 1996 and in piano in 1997. He got his Ph.D.
in Physics in 2000 with a thesis on the “First observation of the
associated charm production in neutrino interactions”, where he firstly
observed this process in the data collected by the CHORUS experiment at
CERN. He is Full Professor of Experimental Physics at the University of
Naples.
After studying the charm production in neutrino interactions in CHORUS,
he moved to the OPERA experiment, designed to observe muon to tau
neutrino oscillations, for the first time in appearance mode with a
neutrino beam at CERN and the detector located in Gran Sasso (Italy). In
OPERA he acted as coordinator of the emulsion scanning laboratories from
2008 till 2012, before being appointed Spokesperson. He served this role
from 2012 until the end of the experimental program in 2019. In 2015
OPERA reported the observation of tau neutrino appearance in a muon
neutrino beam with a significance above 5s, while in 2018 final results
were given with more than 6s significance and with the estimate of the
oscillation parameters with an improved accuracy. In 2018 he patented
with members of his group in Naples a method to achieve nanometric
accuracy with optical microscopy, getting the unprecedented resolution
of 60 nm. In 2018, he did some feasibility studies to build a detector
and study neutrinos for the first time produced by a collider, the LHC.
These studies laid the foundations of the "Scattering and Neutrino
Detector at the LHC” experiment, with 180 scientists in 13 Countries and
CERN. In 2020 he was elected as the first Spokesperson of the experiment.
