The abstract, sentence by sentence
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 non-negligible electroweak corrections in bosonic decays of sbottom, stop and stau.

For this reason, several tools dedicated to the computation of decay rates in the context of specific beyond the Standard Model theories have been developed in the past [ref] , while many Monte-Carlo event generators are also able to compute partial widths on their own via a dedicated phase-space integration [ref] .
