Help with MadSTR
Dear Experts,
I am using the model file SMEFTatNLO with version 3.4.0 of Madgraph. For my work, I need the contribution of four quark operators at the one-loop level, and the authors of the model suggested, and I quote, "The 2. X.X series of MadGraph5_aMC@NLO cannot handle four-quark operators at one-loop". But for my work, I am also considering processes like p p > t w, where at NLO, there is a resonant top quark effect. To take care of those effects, I tried using MadSTR, but it shows the following error "Plugin PLUGIN.MadSTR is not supported by this version of MG5aMC." I checked the earlier queries and came to know that MadSTR at present can only work up to version 2 of Madgraph.
Is there any alternate way to implement the DR/DS procedures to take care of these resonant effects? Any suggestion is appreciated.
Thanks,
Rameswar
