Seminarium "Teoria cząstek elementarnych i kosmologia"

After the discovery of a Higgs boson by the LHC experiments in 2012, one important quest for particle physics is to determine whether the scalar sector realized by nature corresponds to the one described by the Standard Model, or whether it is part of a more involved theory including additional matter content. In addition, astrophysical observations indicate the existence of dark matter, which cannot be explained by the SM alone. In this talk, I will talk about possible extensions of the SM scalar sector, which agree with current measurements and can be investigated at current and future colliders, rendering novel signatures. I will also discuss possible interplay of collider and astrophysical observations.
