help choosing model file
Asked by
Rameswar Sahu
Hi,
I want to study a process in which i have b quarks in the initial state. The process that i want to generate is P P > final state... i want to know which of the following method is correct,
1) work with four flavour scheme
define p = p b b~
generate p p > final state
OR
2) Work in five flavour scheme
generate p p > final state
whichever is the answer can you please give me a good reason...
My only doubt is , if i am generating a process for p p collision where i have b quark in initial state, then should i take the b quark to be massless???
best
