Yukawa induced radiative corrections to the lightest Higgs boson mass in the NMSSM

摘要

We compute the leading logarithmic radiative corrections to the lightest Higgs mass in the NMSSM involving the electroweak gauge couplings and the NMSSM specific Yukawa couplings lambda and kappa (including all mixed combinations), which are induced by chargino, neutralino and Higgs boson loops. The effect of the NMSSM specific Yukawa couplings lambda and kappa is to increase the upper bound on the lightest Higgs mass by up to similar to 1 GeV, but they can also decrease the lightest Higgs mass by up to similar to -20 GeV.
