FeynRules SM and MG5 SM lead to different results
Hello all,
I'm doing some model testing using FeynRules to generate the UFO file for MG5. I was getting some strange results with my new model when setting the pertinent parameters to the limit that would give me the SM back. The strange results are different cross sections for a certain process. So I've decided to create the SM UFO to compare with the SM model that comes with MG5, using the following process:
p p > z h a , h > b b~ , z > l+ l- for sqrt(s)=14TeV
And I get the following results:
with FeynRules SM [massless u,d,s,c and full-CKM] - > xs = 3.063e-4 pb
with "sm" model (default from MG5) -> xs = 1.981e-4 pb
My parameters and run_card variables are the same for both processes. So what is it that I'm missing?
Thanks,
