摘要
We present the one-loop corrected decay widths for the decays of the neutral Higgs bosons h(0), H-0 and A(0) into a neutratino pair (chi) over bar (0)(m) (chi) over bar (0)(n) (m, n = 1,..., 4) and to the decay (chi) over bar (0)(m) -->(h(0),H-0, A(0)) + (chi) over bar (0)(n) 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. (C) 2002 Elsevier Science B.V. All rights reserved.
