2015

The measured exclusive ($N_{jet}$ = 0) fiducial cross section in the e$\nu\gamma\gamma$, $\mu\nu\gamma\gamma$ channels together with the combined $\ell\nu\gamma\gamma$ cross section. The first uncertainty shown is the statistical uncertainty on the measurement, the second one is the total systematic uncertainty (excluding the term coming from the luminosity), the third one is the systematic uncertainty coming from the luminosity. A parton to particle correction factor of 0.87 is applied to the MCFM prediction.

The measured inclusive ($N_{jet}\geq$ 0) fiducial cross section in the e$\nu\gamma\gamma$, $\mu\nu\gamma\gamma$ channels together with the combined $\ell\nu\gamma\gamma$ cross section. The first uncertainty shown is the statistical uncertainty on the measurement, the second one is the total systematic uncertainty (excluding the term coming from the luminosity), the third one is the systematic uncertainty coming from the luminosity. A parton to particle correction factors of 0.99 is applied to the MCFM prediction.

Observed and expected 95\% CL limits obtained for the $f_{\mathrm{T0}}/\Lambda^4$, $f_{\mathrm{M2}}/\Lambda^4$ and $f_{\mathrm{M3}}/\Lambda^4$ aQGC parameters for the combination of the two channels. The values of $n = 0,\,1,\,2$ are the exponential choices of the form factor, $\Lambda_{\rm{FF}}$ is fixed to $600$ GeV for $f_{\mathrm{T0}}/\Lambda^4$ and to $500$ GeV for the other parameters. The $n=0$ choice produces the limits without the form factor applied.
