One-loop corrections to neutral Higgs boson decays into neutralinos
Abstract
We present the one-loop corrected decay widths for the decays of the neutral Higgs bosons h0, H0, and A0 into a neutralino pair neum neun (m, n = 1, >..., 4) and to the decay neum -> (h0, H0, A0) + neun. The corrections contain the one-loop contributions of all fermions and sfermions. All parameters are taken on-shell. This requires a proper treatment of the neutralino mass and mixing matrix. The dependence on the SUSY parameters is discussed. The corrections can be large in certain regions of the parameter space.
