Precise Predictions for Higgs Production in Neutralino Decays
Abstract
Complete one-loop results, supplemented by two-loop Higgs propagator-type corrections, are obtained for the class of processes chi0i->chi0j ha in the MSSM with CP-violating phases for parameters entering the process beyond lowest order. The parameter region of the CPX benchmark scenario where a very light Higgs boson is unexcluded by present data is analysed in detail. We find that the decay chi02->chi01 h1 may offer good prospects to detect such a light Higgs boson.
