Yukawa radiative corrections to the triple self-couplings of neutral CP-even Higgs bosons and to the H {sup {yields}} hh decay rate within the minimal supersymmetric standard model

Within the minimal supersymmetric standard model, four self-couplings, {lambda}{sub hhh}, {lambda}{sub hhH}, {lambda}{sub hHH}, and {lambda}{sub HHH}, and the decay rate {gamma}(H {sup {yields}} hh) are calculated with allowance for one-loop corrections induced by the contribution of the t, b, and c quarks, the {tau} lepton, and the corresponding superpartners and with the aid of the on-shell renormalization scheme. An analysis of the dependences of these features on tan{beta} and the mass of the A Higgs boson, M{sub A}, shows that, in a specific region of the model-parameter space, the calculated corrections can make a significant contribution to the couplings and decay rate in the one-loop approximation. The inclusion of the radiative corrections in question is mandatory in reconstructing the Higgs potential.
