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.

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...
+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.
