Cross sections for new physics
Asked by
Christopher Marino
I am trying to define the couplings for a standard model extension. I want to define qballs (i.e. multi-charged, massive exotic particles) produced via Drell-Yan. I can set the user defined coupling in a version 4 model similar to that of muons produced via Drell-Yan but then the cross-section does not change with higher charges. Is there a more elegant or official way of producing these samples than to enter a factor of charge into the user defined coupling? Is there any to determine when multiplying by a factor of the charge ceases to valid, ie for charges 5 or 6?
Thanks for your help.
