Again the sensitivity is driven by [[http://www.hep.ucl.ac.uk/~jmb/Work/LH/NSCPO/8TeV/mP_80_f0_7500/contur-plots/ATLAS_2016_I1448301_NU/index.html|this paper]], but now it is the $\gamma\gamma + E_T^{\rm miss}$ cross section that does the work. | + | > [[http://www.hep.ucl.ac.uk/~jmb/Work/LH/NSCPO/8TeV/mP_80_f0_7500/contur-plots/|Page of plots]]: This point is chosen to look at the higher end of the $M_\phi$ range, where the sensitivity is greater, and so we look at a high $\Lambda$ value.

And again once the 7 TeV data are included, the inclusive and diphotons cover this point on their own. |

| Note that the sensitivity at low $M_\phi$ and $\Lambda$ is somewhat reduced, especially for the $E_T^{\rm miss} + \gamma$ channel. Presumably something to do with the angular distributions of the decay photons of the $\phi$, but to be studied... | Note that the sensitivity at low $M_\phi$ and $\Lambda$ is somewhat reduced, especially for the $E_T^{\rm miss} + \gamma$ channel.

| + | There is still 95% exclusion even at the highest $\Lambda$ values studied. Would be interesting to see how far it goes. Update - not very far? Here's an 8 TeV run going to higher values. | ||
