Measurement of psi (2S) polarisation in pp collisions at root s=7 TeV

LHCb collaboration

Research output: Contribution to journalArticleAcademicpeer-review


The polarisation of prompt mesons is measured by performing an angular analysis of decays using proton-proton collision data, corresponding to an integrated luminosity of 1.0, collected by the LHCb detector at a centre-of-mass energy of 7 TeV. The polarisation is measured in bins of transverse momentum and rapidity in the kinematic region and , and is compared to theoretical models. No significant polarisation is observed.
