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

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 λ and κ (including all mixed combinations), which are induced by chargino, neutralino and Higgs boson loops. The effect of the NMSSM specific Yukawa couplings λ and κ is to increase the upper bound on the lightest Higgs mass by up to ∼1GeV, but they can also decrease the lightest Higgs mass by up to ∼−20GeV.
