03 Mar '23

Hello everyone, After a never-ending discussion to set the date of our new JC, we decided to organize the first one on Tuesday 21/02 at 2PM. I will be talking about the recent proposal for the formation of PBH from FOPTs discussed in https://arxiv.org/abs/2106.05637 and https://arxiv.org/pdf/2212.14037.pdf. I hope to see you, Best, Miguel

tomorrow Friday
by Alberto Mariotti 09 Feb '23

Dear All, tomorrow there will be construction works in front of the IIHE, on the side of the office of Kevin/Alba/Hannah. The noise should be present only in the morning, but most probably it will go a bit on also in the afternoon. The visitor Fabrizio Rompineve will be around all day and give us a talk about "GW signatures at PTA", blackboards plus slides, at 14:00 https://indico.iihe.ac.be/event/1716/ <https://indico.iihe.ac.be/event/1716/> Given the constructions, there are two options: 1) If the noise on our side (esplanade) is ok, then I propose I can host Kevin/Alba/Hannah/Xander in our offices (and in our seminar room). The seminar then will go on in the small seminar room (1G012) as planned. 2) If the noise is too strong also on our side (esplanade), than we will all move on the 9th floor, building F, where we will have access to some office common space. Thanks a lot to Nina and Alex for making this possible. The seminar will then go on into the small seminar room of the 9F. Tomorrow morning when I will arrive (9:30), I will see what will be the best option, either 1 or 2. Best, Alberto #---------------------------------------------------------------------# Alberto Mariotti Vrije Universiteit Brussel (VUB) https://we.vub.ac.be/HEPVUB <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 #---------------------------------------------------------------------#

The seminar will take place at 12:30 in the room 2NO.708 on the 7th floor of the NO building at ULB. > > Fabrizio will talk about > > QCD axion production in the early Universe > > with the following abstract: > > A population of relativistic QCD axions can be produced in the early Universe, via scatterings with Standard Model particles. This can be searched for in cosmological datasets, which therefore provide the opportunity to discover/constrain the QCD axion, independently of astrophysical and/or laboratory probes. > In this talk, after reviewing the subject, I present an improved calculation of the relic abundance of such “hot” axions from scatterings with pions below the QCD crossover, as well as the resulting upper bound on the QCD axion mass. I then discuss the exciting outlook of upcoming cosmological surveys, which may probe otherwise unexplored regions of the QCD axion parameter space. I highlight the need of a non-perturbative calculation of axion production rates throughout the QCD crossover, to fully exploit the reach of such datasets. > > I am very much looking forward to seeing you there! > > Best, > Marco > > > You're receiving this message because you're a member of the GRP_ULB_JC_Add group from Université Libre de Bruxelles.
