Hi everyone, I was wondering, is the cross section at Eq 50.25 in
http://pdg.lbl.gov/2017/reviews/rpp2017-rev-cross-section-formulae.pdf
correct?
Because I see a term in the denominator with [itex]\frac{1}{s\Gamma}[/itex] whereas in several other references, the propagator term in the matrix element comes with [itex]\frac{1}{M \Gamma}[/itex].
[eg. eq29 here http://article.sciencepublishinggroup.com/pdf/10.11648.j.ijhep.20150205.11.pdf and I can give a further list]
Thanks.
