Main Question or Discussion Point
Hi all,
Do any one familiar with these analysis of cross section ?
I wonder how to find the cross section of ( p p ## \to \gamma \gamma## b b~) (blue region) in the opposite plot, the yaxis is the number of events divided by 100 GeV with luminosity = 100 ##\mbox{fb}^{−1 }##..
The Fig. from [arXiv:1601.07934 [hepph]]. It's known that ## \sigma \times ## luminosity = Number of events, and also ## \mbox{GeV}^{−2}=0.3894~ \mbox{mb}=0.0389~ \mbox{fm}^2 ##, but i still stuck to find sigma at 250 for instance ..
