Z(gamma) production and limits on anomalous ZZ(gamma) and Z(gamma gamma) couplings in p(p)over-bar collisions at root s 1.96 TeV
We present a measurement of p{bar p} {yields} Z{sub {gamma}} {yields} {ell}{sup +}{ell}{sup -}{sub {gamma}} ({ell} = e, {mu}) production with a data sample corresponding to an integrated luminosity of 6.2 fb{sup -1} collected by the D0 detector at the Fermilab Tevatron p{bar p} Collider. The results of the electron and muon channels are combined, and we measure the total production cross section and the differential cross section d{sigma}/dp{sub T}{sup {gamma}}, where p{sub T}{sup {gamma}} is the momentum of the photon in the plane transverse to the beam line. The results obtained are consistent with the standard model predictions from next-to-leading order use ttransverse momentum spectrum of the photon to place limits on anomalous ZZ{gamma} and Z{gamma}{gamma} couplings.
