Seminarium "Teoria cząstek elementarnych i kosmologia"

In spite of its success in describing the properties of the discovered elementary particles, including the scalar resonance recently identified at the Large Hadron Collider as the Higgs boson, the Standard Model cannot provide satisfactory answer to some issues, like for example the presence of dark matter, the masses of the neutrinos, the gauge-hierarchy, the number of fermionic families... We present some extensions of the Standard Model that can be testable at colliders in the near future. In particular we discuss the signatures of these BSM models in multileptonic final states.
