英文摘要: We examine various direct and indirect experimental constraints on the nearly minimal supersymmetric standard model (nMSSM) and obtain the following observations: (i) Current experiments stringently constrain the parameter space, setting a range of 1 similar to 37 GeV for the lightest neutralino (chi) over tilde (0)(1), 30 similar to 140 GeV (1 similar to 250 GeV) for the lightest CP-even (CP-odd) Higgs boson, and 1.5 similar to 10 for tan beta; (ii) To account for the dark matter relic density, besides the s-channel exchange of a Z boson, the s-channel exchange of a light A(1) (the lightest CP-odd Higgs boson) can also play an important role in lightest supersymmetric particle annihilation. Compared with the Z-exchange annihilation channel, the A1-exchange channel is more favored by muon g - 2 data and allows much broader regions for the parameters; (iii) In a large part of the allowed parameter space the SM-like Higgs boson may dominantly decay to (chi) over tilde (1)(0)(chi) over tilde (1)(0) or A(1)A(1) and the conventional visible decays (e. g. into bottom quarks) are severely suppressed.
