Complete one-loop corrections to decays of charged and CP-even neutral Higgs bosons into sfermions

We present the full one-loop corrections to charged and CP-even neutral Higgs boson decays into sfermions including also the crossed channels. The calculation was carried out in the minimal supersymmetric extension of the Standard Model and we use the on-shell renormalization scheme. For the down-type sfermions, we use DR running fermion masses and the trilinear coupling Af as input. Furthermor...

Fermionic decays of sfermions: a complete discussion at one-loop order

We present a definition of an on-shell renormalization scheme for the sfermion and chargino-neutralino sector of the Minimal Supersymmetric Standard Model (MSSM). Then, apply this renormalization framework to the interaction between charginos/neutralinos and sfermions. A kind of universal corrections is identified, which allow to define effective chargino/neutralino coupling matrices. In turn, ...

Fermionic decays of neutral MSSM Higgs bosons at the one - loop level ∗

The results of a complete one-loop calculation for the fermionic decay width Γ(h 0 , H 0 , A 0 → f ¯ f) of the neutral MSSM Higgs bosons are presented and the dominant light Higgs decay channel h 0 → b ¯ b is discussed in detail. The enhancement of Γ(h 0 → b ¯ b) compared to the standard Higgs decay is shown for pseudoscalar masses M A ≤ 300 GeV, where the one-loop contributions in the MSSM and...

Full one-loop corrections to sfermion decays

We analyze the partial decay widths of sfermions decaying into charginos and neutralinos Γ(f̃ → f ′χ) at the one-loop level. We present the renormalization framework, and discuss the value of the corrections for topand bottom-squark decays.

SFOLD - A program package for calculating two-body sfermion decays at full one-loop level in the MSSM

SFOLD (Sfermion Full One Loop Decays) is a Fortran program package for calculating all sfermion two-body decay widths and the corresponding branching ratios at full one-loop level within the MSSM. The package adopts the SUSY Parameter Analysis convention and supports the SUSY Les Houches Accord input and output format. With the SFOLD package we found nonnegligible electroweak corrections in bos...
