# Some of bins when on plots are empty

Hi!

I'm modeling the process p b > b b~

for, say, Sqrt[s] = 13 TeV, 0 < p_T < 100 GeV, 0<eta < 2.1

Parameters for plot of p_T: 40 0 100 What is the reason for some bins at large p_T being empty (while for the left and for the right there are filled bins)? Sorry for this stupid question...

Hi,

Naively, I would say that you may have poor statistics in the large PT regime.

Regards,

Benjamin
