Dear All, The hep@vub group is organising a poster session on October 26 here at VUB, with some drinks, in a nice atmosphere to know more our young and not-young colleagues working on high-energy at VUB. It would be nice to participate, it starts at 16:30 so it will be really the end of your working day. If you have an already prepared poster (Hannah for instance), you could also present it. See here below and please register.

The limit on QCD theta angle is 2 * 10^(-8) and somewhat subdominant to neutron EDM, but can be improved. The Kobayashi-Maskawa phase contributes to paramagnetic EDMs at the level of 10^{-35} e cm in units of equivalent electron EDM, which is much larger than what was previously estimated. > ———————————————— > > Seminars and Journal Clubs agenda: http://cp3.irmp.ucl.ac.be/PAI/month.php <http://cp3.irmp.ucl.ac.be/PAI/month.php> > > ================ > ULB PhysTH Seminar by Maxim Pospelov (U. of Minnesota), 'Standard Model and EDMs', Room 2.N7.110 [BEL-center:pheno] > Dates : 1 sept. 2023, 11:00-12:00, UTC+2 > ================ > > > You're receiving this message because you're a member of the GRP_ULB_Sem_Add group from Université Libre de Bruxelles.

The school is aimed to provide a pedagogical introduction to lattice field theory techniques and their use to simulate the classical dynamics of interacting fields in an expanding background. The lectures will serve as an introduction to COSMOLATTICE, a public code developed for lattice simulations of early Universe scenarios. The use of CosmoLattice as a tool to simulate scalar and gauge field non-linear dynamics in an expanding universe will be presented in full detail. Modern applications to inflation, preheating, gravitational wave production, non-minimally coupled scalar field dynamics, axion-like field dynamics, and possibly others, will also be covered. The school is aimed to anyone who would like to learn (or simply improve their knowledge on) how to simulate in a lattice the dynamics of early Universe field theory scenarios. > > Registration will be open till Sept. 5th 2023, see > > https://indico.ific.uv.es/event/7055/ <https://indico.ific.uv.es/event/7055/> > > Observations: The school will be held ONLINE, during 25-29 Sept 2023.

seminar Yann Gouttenoire Tuesday 27 June at 14:00
by Alberto Mariotti 26 Jun '23

26 Jun '23

Dear All, I'm happy to announce the seminar of Yann Gouttenoire (Tel Aviv University) next week Tuesday 27 June at 14:00 in the room G.1.03 - J. Sacton (Building G) at IIHE. Here the webpage of the event: https://indico.iihe.ac.be/event/1797/ Yann will talk about: Title: Primordial black holes from supercooled phase transition and implications for Pulsar Timing Arrays Abstract: Cosmological first-order phase transitions are said to be supercooled when the nucleation temperature is much smaller than the critical temperature. They are typical of potentials which feature nearly scale-invariance, for which the bounce action decreases only logarithmically with time. The phase transition takes place slowly and the probability distribution of bubble nucleation time is maximally spread. Hubble patches which get percolated later than the average are hotter than the background after reheating and potentially collapse into primordial black holes (PBH). In the first part of the talk, I will discuss the formation of PBH by supercooled phase transitions. In the second part, I will discuss the search for supercooled phase transitions in pulsar timing arrays and how it affects the search for PBH in LIGO-Virgo. Yann will be visiting us from Tuesday to Friday, so there will be plenty of time for discussions.
