Wednesday, May 16
Time: 12:30 PM - 1:30 PM
Summary: ULB seminar: Filippo Sala "Dark Matter from Dark Sectors: self interactions and beyond"
Description:
I will discuss some phenomenological consequences of extensions of the Standard Model containing a mediator lighter than the Dark Matter.
A first example is that of DM self interactions, as a solution to putative discrepancies between collisionless cold DM and observations of galactic structures.
I will show how this possibility is in tension with indirect detection constraints (from the CMB, gamma-rays and antiprotons), and what are the challenges to evade them via the introduction of an asymmetry in the DM population.
A second example is that of dilution of the DM abundance via late decays of the mediator, that allows to evade the so-called unitarity bound.
This enriches the physics case of several ongoing and planned telescopes (HESSII, HAWC, CTA, ANTARES, IceCube, KM3NeT, CALET,...) observing cosmic rays at and beyond 100 TeV.

Friday, May 18
Time: 11:00 AM - 12:00 PM
Summary: ULB Seminar: Belen Gavela - "On axions and ALPs"
Description:
I will first discuss axions and axion-like particles (ALPs) in general, with new physics developments. I will then discuss the model-independent leading effective interactions between the SM fields and a generic ALP. Two frameworks for electroweak symmetry breaking are considered: linear and non-linear. For the latter case, the basis of leading effective operators is determined. For both scenarios, associated novel signals at colliders involving gauge bosons or the Higgs boson are determined and analyzed. In the second part of the talk, I will present a model with an enlarged color sector which solves the strong CP problem via new massless fermions. QCD colour is unified with another confining group with a large confining scale. Small size instantons provide an extra source of masses for axions, which become heavy. Massless sterile fermions in the low energy spectrum are instead a singular characteristic. The axion scale may be near the TeV region which results in QCD-coloured scalars
