O ct 2 00 8 Higgs mass bounds from a chirally invariant lattice Higgs-Yukawa model with overlap fermions HU-EP-08 / 52 DESY 08-158

We study the parameter dependence of the Higgs mass in a chira lly inv riant lattice Higgs-Yukawa model emulating the same Higgs-fermion coupling structure as in the Higgs sector of the electroweak Standard Model. Eventually, the aim is to establish upper and lower Higgs mass bounds. Here we present our preliminary results on the lower Higgs ma s bound at… (More)
