little bit about mass distributions phenomenology
Asked by
Safinaz
Dear authors,
I'm working on studying pp > S0 S0 > bb~bb~ process where S0 is a neutral octet scalar of mS = 2 TeV ..
generated two plots pf m(b,b~) versus the cross section(pb/bin) and versus number of events ..
I noticed that the plot of cross section(pb/bin) is a distribtuion starting from around 750 GeV, while
the plot of number of events is adistribution has a small peak at 2 TeV .. which is fine .. so why this peak dosn't
appear at the cross plot as on-shell decay of S0 .. like for example pp> tt~H, H>bb~ process in SM .. is that because I have in my process 4 b .. if so why the events plot differes from the sigma plot ?
Bests,
Safinaz
