1  Based on 35.9 fb${}^{-1}$ of proton-proton data taken at $\sqrt {s }$ = 13 TeV. The result is consistent with the SM prediction and is used to constrain the Wilson coefficients for dimension-six operators describing new interactions. The result is consistent with the SM prediction at NLO $0.839$ $\pm0.101$ pb.
