We consider a modified cosmological history in which the new physics causes the electroweak gauge sector, $SU(2)_L$, to confine before it is Higgsed and before the strong force confines. Eventually, the universe leaves this confining $SU(2)_L$ phase and returns to the phases we know to be present from BBN. In the confining $SU(2)_L$ phase, we argue that the quark and lepton...
Despite the vast literature on first order Electroweak Phase Transitions (EWPT), which can provide the necessary conditions for generating the Baryon Asymmetry in the Universe, fermion-induced EWPTs still remain a rather uncharted territory. In this talk, we consider a simple fermionic extension of the Standard Model (SM) involving one SU(2)L doublet and two singlet Vector-Like Leptons (VLLs),...
