An angular analysis of the decay / → is performed to measure the polarization of prompt / mesons produced in collisions at [Formula: see text]. The dataset corresponds to an integrated luminosity of 0.37 fb collected with the LHCb detector. The measurement is presented as a function of transverse momentum, , and rapidity, , of the / meson, in the kinematic region 2< <15 GeV/ and 2.0< <4.5.
