Abstract
he first observation of Z boson production in proton-lead collisions at a centre-of-mass energy per proton-nucleon pair of sNN‾‾‾‾√=5 TeV is presented. The data sample corresponds to an integrated luminosity of 1.6 nb−1 collected with the LHCb detector. The Z candidates are reconstructed from pairs of oppositely charged muons with pseudorapidities between 2.0 and 4.5 and transverse momenta above 20 GeV/cFile in questo prodotto:
