Motivation◮ A heavy 4th gen. of quarksruled out.(t ′b ′ )has not been (completely)◮ Large m t ′ ,b ′ means large y t ′ ,b′. Perturbative methods may notwork.◮ Lattice field theory enables study of the Higgs-Yukawa sector(NO gauge fields) at large y.◮ Effects on the Higgs boson mass bounds from a possible 4Gare timely.◮ Effects on the thermal phase transition may be relevant forelectroweak baryogenisis.
