Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I try to calculate the Higgs production cross section by Mathematica using

for example the formula in [arXiv:hep-ph/0503172].

The problem comes when I calculate " σ_0 " it's of order 10^-10 pb at mh = 125 GeV ( 3.57), then when I convolute with the parton distribution function to get the pp -> H production according to equ.( 3.58) it gives me of order 10^-7 pb !! while in the plot (3.18) pp -> H is around 50 pb.

I don't know what is the problem I have, any help please.

Best,

Safinaz
