SMEFTsim does not implement csin2_thetaW
While the conversion of the SMEFTsim UFO file to a Sherpa model proceeds fine, the resulting Model is not what all parts of Sherpa expect. Partonic calculations work fine with Comix, but the CSShower cannot convert the model into its splitting functions for two reasons:
- The constant csin2_thetaW is not implemented (interestingly) but used later, eg. in the EW splitting functions.
- All CSS splitting functions are doubled.
The SMEFTsim UFO model is attached, as is a simple run card.
