Measurement of electroweak-induced production of Wγ with two jets in pp collisions at √s=8 TeV and constraints on anomalous quartic gauge couplings

A measurement of electroweak-induced production of Wγ and two jets is performed, where the W boson decays leptonically. The data used in the analysis correspond to an integrated luminosity of 19.7 fb−1 collected by the CMS experiment in √ s = 8 TeV proton-proton collisions produced at the LHC....
