摘要
A search for associated production of a Z boson with an open charm meson is presented using a data sample, corresponding to an integrated luminosity of 1.0 fb −1 of proton-proton collisions at a centre-of-mass energy of 7TeV, collected by the LHCb experiment. Seven candidate events for associated production of a Z boson with a D 0 meson and four candidate events for a Z boson with a D + meson are observed with a combined significance of 5.1 standard deviations. The production cross-sections in the forward region are measured to be [ _Z→^+_^-_,D^0=2.50± 1.12± 0.22 pb; _Z→^+_^-_,D^+=0.44± 0.23± 0.03 pb,; ] where the first uncertainty is statistical and the second systematic.
