On effective lumionsity in PbPb and pp runs
Hi,
I am studying some new physics model in pp and in PbPb collisions. For the PbPb runs I modify the mg5 card as follows:
--set pdlabel lhapdf
--set lhaid 901300
--set ebeam1 2750*208
--set ebeam2 2750*208
I realized during the runs that I get effective luminosity for the PbPb run=0.6pb^-1 while for pp=233pb^-1. I don't understand how I should interpret these numbers.
Ultimately, I want to compare the number of events in PbPb and in pp for equal running time at the LHC. For that, and at a later step, I scale the number of events by the integrated luminosity corresponding to a month of running the LHC at pp, and the same for PbPb.
Now that I saw those effective lumionsity numbers produced by mg5, I am not sure how I should scale the number of events, given that mg5 is already considering different luminosity in both cases. May you please elaborate on that?
Best,
Hesham
