Abstract: (APS)
We numerically study the regularization dependence of the upper bound on the Higgs-particle mass MH(phys) by varying the lattice type and interaction. Computing fπ and λr where the scalar mass is ∼ 1, we find the bound MH(phys)<620 GeV. However, there is a small but systematic increase in the bound as the coordination number of the lattice increases. Hence, it is not meaningful to quote error estimates on such bounds.- talk
