Main Question or Discussion Point

Hi all,

Any help about interprting the results of ## \sigma(pp \to H) \times BR (H \to WW) ## mentioned in Fig.(12-13) in [arXiv:1509.00389[hep-ex]]?

In that paper [arXiv:1512.06728v3[hep-ph]], page 8, its said that according to these figuers ## \sigma ( pp \to H \to WW^* )\leq 54, 37 fb ##, but I don't undersatnd how can we conclude that ?
also why in this paper they say WW* although the results in the Figs for WW both decay lepotonically ..


Cheers,
S.

That should be directly the exclusion limit given by ATLAS, read off at 750 GeV. How ATLAS concluded that: standard CLs technique.

also why in this paper they say WW* although the results in the Figs for WW both decay lepotonically ..
The (optional) * is just a reminder that one W is far off-shell.

Can't we understand form the figures any informatin ?

I mean as in [arXiv:1512.06728v3[hep-ph]], they say that : they concluded from these fig (12-13) that
## \sigma ( pp \to H \to WW^* )\leq 54, 37 fb ## .. I were asking from the begining how they reached to this conculution , i.e., how can we interpret the Exp. graphes ?

The referenced graphs directly show the exclusion limits: the y axis is the cross-section, the solid line is the exclusion limit as function of the mass (x axis). To find the exclusion limit at 750 GeV, look at the y-value of the solid line for x=750 GeV.
