dc.description.abstract	An angular analysis of the decay J/ψ→μ + μ − is performed to measure the polarization of prompt J/ψ mesons produced in pp collisions at s√=7 TeV. The dataset corresponds to an integrated luminosity of 0.37 fb−1 collected with the LHCb detector. The measurement is presented as a function of transverse momentum, p T, and rapidity, y, of the J/ψ meson, in the kinematic region 2<p T<15 GeV/c and 2.0<y<4.5.	eng
