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

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)

Abstract
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 b ̃ , t ̃ and τ ̃ .

Title of program: SFOLD
Catalogue Id: AEMZ_v1_0

Nature of problem
If the MSSM is realized in nature, LHC will produce supersymmetric particles copiously. The best environment for a precise determination of the model parameters would be a high energy e + e - linear collider. Experimental accuracies are expected at the per-cent down to the per-mill level. These must be matched from the theoretical side. Therefore loop calculations are mandatory.

摘要：SFOLD（Sfermion Full One-Loop Decays）是一款Fortran程序包，旨在计算所有sfermion双体衰变宽度及其在MSSM（Minimal Supersymmetric Standard Model，最小超对称标准模型）框架下全一环阶次对应的分支比。该程序包遵循SUSY参数分析惯例，并支持SUSY Les Houches协定的输入输出格式。借助SFOLD程序包，我们发现b~、t~和τ~的玻色子衰变中存在不可忽略的电弱修正。

目录编号：AEMZ_v1_0

问题性质：若MSSM在自然界中得以实现，大型强子对撞机（LHC）将大量产生超对称粒子。精确确定模型参数的最佳环境为高能电子正负电子对线性对撞机。预期实验精度将达到百分之一至千分之一的水平。这些精度必须从理论方面进行匹配。因此，循环计算是必不可少的。
