Triviality bound on lightest Higgs mass in next to minimal supersymmetric model
S R Choudhury Mamta Sukanta Dutta
We study the implication of triviality on Higgs sector in next to minimal supersymmetric model (NMSSM) using variational field theory. It is shown that the mass of the lightest Higgs boson in NMSSM has an upper bound ∼10
