Hello everyone, second try for the JC on VIA sources this tuesday 04/04 at 2pm. The first message was: I (AGAIN!) will talk about https://arxiv.org/pdf/2206.01120.pdf which claims to rule out VIA sources for EWBG and puts now usual EWBG scenario at odds with EDM measurements. Maybe we can try a discussion on alternatives to usual EWBG mechanism. Best, Miguel

visitors of our group in the upcoming months
by Alberto Mariotti 29 Mar '23

29 Mar '23

Dear All, here a list of confirmed visitors/speakers that will visit our group in the coming period. Oriol Pujolas (from IFAE). He will come one-day, giving a talk, on the 27 of April. Unfortunately he can be present only on that day for family reasons. He works on DW and many aspects of GW related to our interests, so I encourage you to be present on that day. Diego Redigolo (Firenze University). He will visit jointly VUB and ULB from 22 to 26 May. Diego is a long-term collaborator of mine about pheno aspects of SUSY. He is working now on cosmological perturbations, and he will give a talk on such topic on Thursday or Friday of that week. Yann Gouttenoire (Tel Aviv University). He will visit us from 26 to 30 June. He is an expert on phase transitions and cosmic strings. He will present us his work on Monday or Tuesday of that week (still to be defined). Best, Alberto #---------------------------------------------------------------------# Alberto Mariotti Vrije Universiteit Brussel (VUB) https://we.vub.ac.be/HEPVUB Phone: +32 (0) 2 629 32 15 E-mail: alberto.mariotti(a)vub.be Address: Vrije Universiteit Brussel Physics Department Elementary Particles Research Group Pleinlaan 2, 1050 Brussels, Belgium #---------------------------------------------------------------------#

Ioanna kindly volunteered to talk about Ruling Out Primordial Black Hole Formation From Single-Field Inflation based on arXiv:2211.03395. But she will also try to reference papers such as 2301.00599, 2303.01727 and 2303.12025, which claim the opposite. See you there!

27 Mar '23

Hello everyone, Next JC on monday 27, 2pm. We start our series on baryogenesis with Alberto that will talk about a very recent paper: https://arxiv.org/abs/hep-ph/9810261 on baryogenesis from cosmic string and discuss possible ways to extend it to domain walls. My JC on VIA sources for electroweak baryogenesis is postponed, likely to monday 3/04. Hope to see you there, Best, Miguel
