Higgs squared

A bstract We present a novel construction for Higgs-VEV sensitive (HVS) operator, which can be used as trigger operator in cosmic selection models the electroweak hierarchy problem. Our does not contain any degrees of freedom charged under SM gauge symmetries, leading to reduced tuning resulting models. is based on extension two Higgs doublet model (2HDM) with softly broken approximate global D 8 symmetry (the group square). crunching our extended sector has only percent level corresponding usual little In large regions parameter space 2HDM naturally pushed towards alignment limit. complete requires introduction fermionic top partners ensure fermion sector. also show that same implementation seesaw mechanism neutrino masses.
