AAD 2016U based on 20.3 fb${}^{-1}$ of data, using a maximum-likelihood fit of a matrix element method discriminant. The same data set as in AAD 2015A is used. The result corresponds to an observed significance of 3.2 ${{\mathit \sigma}}$ .

KHACHATRYAN 2016AZ based on 19.7 fb${}^{-1}$ of data, using a multivariate analysis to separate signal and backgrounds. The same method is applied to 5.1 fb${}^{-1}$ of data at $\sqrt {s }$ = 7 TeV, giving $7.1$ $\pm8.1$ pb. Combining both measurements, the observed significance is 2.5 ${{\mathit \sigma}}$ . A best fit value of $2.0$ $\pm0.9$ is obtained for the combined ratio of the measured values and SM expectations.

AAD 2015A based on 20.3 fb${}^{-1}$ of data, using a multivariate analysis to separate signal and backgrounds. The 95$\%$ CL upper bound of the cross section is 14.6 pb. The results are consistent with the SM prediction of $5.61$ $\pm0.22$ pb at approximate NNLO.
