IIHE Seminar Mar 22: Dr. James Howarth (Exploring quantum entanglement at hadron colliders using top quarks at the ATLAS experiment)
by Steven Lowette 19 Mar '24

19 Mar '24

Dear all, On Friday Mar 22 we will have an IIHE seminar from Dr. James Howarth: "Exploring quantum entanglement at hadron colliders using top quarks at the ATLAS experiment" 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/1918/ Kind regards, Steven. ----- Abstract: ATLAS recently observed quantum entanglement in pairs of top quarks using 13 TeV data, the first time that entanglement has been observed in fundamental quarks and at the highest ever energy scales. In this seminar I will explain how this ground breaking measurement was achieved, how it highlights limitations in our current state-of-the-art Monte Carlo simulations, and the implications of the result in the wider context of quantum information. I will also explain what direction this exciting new field of study at collider experiments might take and highlight new opportunities for collaborations between quantum information and collider physics. Bio: Dr James (Jay) Howarth is a Lecturer at the University of Glasgow and Royal Society University Research Fellow. He obtained his PhD at the University of Manchester in 2013, followed by a research fellowship at DESY and a postdoctoral research position at the University of Manchester. His research focuses on top quark physics in general, particularly on the properties of top quarks at hadron colliders and is a member of the ATLAS collaboration. -- Steven Lowette https://cern.ch/lowette/

IIHE Seminar Mar 7: Dr. Richard Ruiz (Vector Boson Scattering: Status and Prospects for the Large Hadron Collider and Beyond)
by Steven Lowette 07 Mar '24

07 Mar '24

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: https://indico.iihe.ac.be/event/1917/ Kind regards, Steven. ----- 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. -- Steven Lowette https://cern.ch/lowette/

IIHE Seminar Feb 23: Prof. Giovanni De Lellis (The Scattering and Neutrino Detector at the LHC)
by Steven Lowette 23 Feb '24

23 Feb '24

Dear all, On Feb 23 we will have an IIHE seminar from Prof. Giovanni de Lellis: "The new era of collider neutrinos: the Scattering and Neutrino Detector at the LHC" at 14h00 in the Sacton seminar room (G.1.03) (note the unusual time to accommodate travel constraints) Abstract and short bio are below; the event's agenda can be found here: https://indico.iihe.ac.be/event/1916/ Kind regards, Steven. ----- 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. -- Steven Lowette https://cern.ch/lowette/
