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.
