Also once the 7 TeV data are included, the inclusive and diphotons cover much of the parameter space on their own. |

| - | Note that the sensitivity at low $M_\phi$ and $\Lambda$ is somewhat reduced. Cause to be investigated. The 7 TeV inclusive photon results are needed to fill in the lower left corner. | + | 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... |
| - | Remember, big caveat on all this is the standard Contur assumption (at the moment) that the data exactly agree with the SM, which means (given we only really know that these data are //consistent// with the SM) that we are neglecting the SM theory uncertainties. | + | |
