Hi, Indeed the model MSSM_SLHA2 can only support LO computation. If you are interested in LO computation, then you can just remove the two line: > True = reweight_scale > False = reweight_PDF From your card and have the LO result with the variation that you ask for. If you are interested in NLO computation, then you have to use a NLO ready model. I do not think that full MSSM model exists but some sector are implemented. I would suggest to check the model avaiable on the FeynRules website. Cheers, Olivier > On 28 Aug 2017, at 16:08, Amin Aboubrahim
