What can the 4G do for me? (Holdom et al, ‘08)◮ Alleviate tension btw. EW fits of M H and exclusion bounds◮ Dark matter candidate◮ More CKM phases → more CP violation◮ Enforces R-parity in MSSM (Wise, et al)◮ Possibilities of a UV fixed point (P.Q. Hung, et al)
Two questions we will ask:◮ How does the 4G affect Higgs boson mass bounds?◮ (Holdom, et al ‘08): Allowed range decreases with mf◮ Does this hold up non-perturbatively?◮ How does the 4G affect the EW-phase transition?◮ (Laine, et al ‘96): Gauge-Higgs models unsuitabe for EWbaryogenisis◮ Can large yukawas induce a 1st order transition?
