Details about the MSSM at NLO implementation in FeynRules

Description of the model & references

In contrast to the leading order MSSM implementation in FeynRules, the NLO MSSM implementation does not allow for inter-generational sfermion mixing and CP-violation beyond the one included in the CKM matrix. The implementation relies on the superspace capabilities of FeynRules (see arXiv:1102.4191) and follows the SUSY Les Houches accord (version 1). As there is some freedom in the way the model renormalisation in the on-shell scheme can be implemented, the user is free to implement his/her own by making use of a FeynRules plugin called MoGRe. A few examples of usage can be found below and in arXiv:1907.XXXXX.
