Effect of changing the mass of top quark on cross section

Asked by Muhammad Irfan

Hi

I am trying to calculate the cross section of t t-bar(fNLO) at different mass of the top quark. But it give me the linear relation of cross section with changing the value of mass. shall the value peak at some value/point? Or the linear relation is ok .
Thank you
Muhammad Irfan

Hi,

The cross-section should decrease when increasing the top mass. Not sure if the relation is as simple as linear but a peak certainly not.

Cheers,

Olivier
