Friday, February 3
Time: 11:00 AM - 12:00 PM
Summary: ULB Seminar: Farinaldo Queiroz - Dark Matter Overview: A step toward the nature of dark matter.
Description: We review the evidence and search for dark matter and summarize the current status of the field. Lastly, we discuss how one could possibly determine the fundamental nature of dark matter using only direct detection experiments.

Friday, February 10
Time: 11:00 AM - 12:00 PM
Summary: ULB Seminar: Jérémie Quevillon - The Fermi Theory of the 21st Century
Description: In this talk, we present the universal one-loop effective action for all operators of dimension up to six obtained by integrating out massive, non-degenerate multiplets. Our general expression may be applied to loops of heavy particles. The broad applicability of this approach simplifies one-loop matching from an ultraviolet model to a lower-energy effective field theory (EFT), a procedure which is now reduced to the evaluation of a combination of matrices in our universal expression, without any loop integrals to evaluate.
We illustrate the relationship of our results to the Standard Model (SM) EFT, using as an example the supersymmetric stop and sbottom squark Lagrangian and extracting from our universal expression the Wilson coefficients of dimension-six operators composed of SM fields.
We then discuss the present and possible future indirect constraints on stop masses and on others well motivated Beyond the Standard Model theories.

Time: 11:00 AM - 12:00 PM
Summary: ULB Seminar: Ye-Ling Zhou - From leptonic flavour models to lepton asymmetry in the Early Universe
Description: We propose a new mechanism of leptogenesis based on the flavour phase transition. Flavons and flavour symmetries have been widely used to address the lepton flavour mixing puzzle. Flavons get VEVs, resulting in flavour symmetry breaking and leading to flavour mixing and CP violation. During the flavour-symmetric phase transiting to the broken phase, the coupling of the Weinberg operator is time-dependent, and a lepton asymmetry is generated by the interference of Weinberg operators at different times. This mechanism differs from the classical thermal leptogenesis in type-I seesaw, where the lepton asymmetry is generated through the decay of right-handed neutrinos. It provides strong connections with low-energy neutrino experiments and leptonic flavour models.

Summary: ULB Seminar: Chris KOUVARIS - The hunt for Dark Matter: From Stars to Detectors
Description: Light dark matter is difficult to probe experimentally in direct search experiments because of low kinetic energies that cannot trigger detectors and also due to neutrino background that can fake the dark matter signal. I will discuss various possibilities that can alleviate the aforementioned problems, facilitating experimental searches of sub-GeV dark matter. I will also discuss the possibility that asymmetric dark matter might form its own compact star-like objects that could potentially be detected via gravitational waves in LIGO.
