"Extended Higgs sectors to solve the matter-antimatter asymmetry of the Universe"
While the discovery of a Higgs boson at the CERN LHC in 2012 was a major achievement for Particle Physics, numerous questions remain unsolved in our understanding of Nature at its most fundamental level. This talk will focus on one specific open issue among these: the explanation of the asymmetry between matter and antimatter in the Universe (or baryon asymmetry of the Universe, BAU). After reviewing the situation in the Standard Model (SM) – our current best theory of fundamental interactions, which can however not explain the BAU – I will discuss the scenario of electroweak baryogenesis and an example of a concrete Beyond-the-Standard-Model (BSM) theory that can generate the BAU, namely the general singlet extension of the SM (RxSM). I will concentrate on experimental probes of the RxSM, and present recent results on the complementarity between data from high-energy colliders and searches for primordial gravitational waves with space-based interferometers.
Alain Verduras has studied physics at the University of Cantabria with a major in fundamental physics. During the third year he did an internship at IFCA analysing CMS collisions together with Jonatan Piedra. And in the fourth year he did his TFG with Jonatan Piedra and Sven Heinemeyer on BSM Higgs physics and phenomenology. At the end of his degree he spent two months at the DESY Summer School working with Georg Weiglein and Johannes Braathen on BSM Higgs Physics. At the end of the summer school he moved to Madrid to do the Master in Theoretical Physics at the IFT where he did the TFM with Sven Heinemeyer continuing the research line of his TFG. After finishing the master's degree he went back to DESY again, this time with a PhD scholarship to do his thesis together with Johannes Braathen and he have been doing his PhD for one year now.
La charla tendrá lugar en la Sala Luis Pesquera del IFCA a las 10:00. Café previo a las 9:45.
