Higgs boson decays into a pair of supersymmetric particles
 pdf 

ABSTRACT

Within the framework of the Minimal Supersymmetric Standard Model, the H, h, A and H± Higgs bosons decay channels into a pair of supersymmetric particles were studied: into a pair of chargino H (h; A )⇒ χ𝑖-χ𝒋+; a pair of neutralino H (h; A ) ⇒ χ𝑖0χ𝒋0; in a pair of chargino - neutralino Н± ⇒ χ𝑖±χ𝒋0; into a pair of scalar fermions H (h; A)⇒ ƒ̃iƒ̃j, Н± ⇒ ƒ̃iƒ̃′j. Analytical expressions for these decays widths are obtained, the degree of longitudinal polarizations of the chargino and neutralino and the dependence of the decay width on the Higgs boson mass are studied in detail.

Keywords: Standard Model, Minimal Supersymmetric Standard Model, Higgs boson, chargino, neutralino, decay width, sfermion.
PACS: 14.80 Da, 14.80 Ly, 14.80 Nb.
