Seminar: Phenomenology of Vector-like Leptons at Next-to-Leading Order

Beyond the three generations of the Standard Model (SM), chiral fermions at the Electroweak scale are already strongly constrained. A tantalizing alternative are vector-like fermions whose Dirac masses and interactions with the SM can strongly modify the standard mass generation via EWSB. 

In this talk I will focus in particular on vector-like leptons and discuss how they lead to strong correlations between the lepton dipole moments and Higgs couplings. I then explain how higher order corrections can be calculated and how they affect these correlations.
