Abstract

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