| 英文摘要 | This paper presents a study of ww gamma and wz gamma triboson production using events from proton-proton collisions at a centre-of-mass energy of root s = 8 tev recorded with the atlas detector at the lhc and corresponding to an integrated luminosity of 20.2 fb(-1). the ww gamma production cross-section is determined using a final state containing an electron, a muon, a photon, and neutrinos (e upsilon mu upsilon gamma). upper limits on the production cross-section of the e upsilon mu upsilon gamma final state and theww gamma and wz gamma final states containing an electron or a muon, two jets, a photon, and a neutrino (e upsilon j j gamma or mu upsilon j j gamma) are also derived. the results are compared to the cross-sections predicted by the standard model at next-to-leading order in the strong-coupling constant. in addition, upper limits on the production cross-sections are derived in a fiducial region optimised for a search for newphysics beyond the standard model. the results are interpreted in the context of anomalous quartic gauge couplings using an effective field theory. confidence intervals at 95% confidence level are derived for the 14 coupling coefficients to which ww gamma and wz gamma production are sensitive. |
