Yukawa radiative corrections to the trilinear self-couplings of neutral CP-even Higgs bosons and decay width $\Gamma (H\to hh)$ in the MSSM

Abstract

The four self-couplings ${\lambda }_{hhh}$, ${\lambda }_{hhH}$, ${\lambda }_{hHH}$, ${\lambda }_{HHH}$ and decay width $\Gamma (H\to hh)$ are calculated taken into account one-loop $t,b,c$ - (s)quarks, $\tau$ - (s)lepton corrections in the framework of the Minimal Supersymmetric Standard Model (MSSM). By the example of self-couplings dependencies from $\mathrm{tg}\beta$ and \textrm{$M_A$}, it is shown, that calculated corrections can give the essential contribution to self-couplings and decay width determined at one-loop level. The radiative corrections account becomes necessary condition for performance of Higgs potential reconstruction procedure and experimental confirmation of Higgs mechanism.
