An Upper Bound on the Higgs Boson Mass from a Positivity Condition on the Mass Matrix
arXiv:hep-ph/9801290 · doi:10.1142/S0217732398000814
Abstract
We impose the condition that the eigenvalues of the mass matrix in the shifted Lagrangian density be positive at ϕ=ϕ_{0}, the vacuum expectation value of the scalar field. Using the one-loop effective potential of the standard model, this condition leads to an upper bound on the Higgs boson mass m_{H}: m_{H}<230GeV, for a top quark mass of 175GeV.
