The production of J/psi mesons with rapidity 1.5 < y < 4.0  or -5.0 < y < -2.5 and transverse momentum p_T < 14 GeV/c is studied with the  LHCb detector in proton-lead collisions at a nucleon-nucleon centre-of-mass  energy sqrt(s_NN)=5 TeV. The analysis is based on a data sample corresponding  to an integrated luminosity of about 1.6 nb^-1. For the first time the nuclear  modification factor and forward-backward production ratio are determined  separately for prompt J/psi mesons and J/psi from b-hadron decays. Clear  suppression of prompt J/psi production with respect to proton-proton  collisions at large rapidity is observed, while the production of J/psi from  b-hadron decays is less suppressed. These results show good agreement with  available theoretical predictions. The measurement shows that cold nuclear  matter effects are important for interpretations of the related quark-gluon  plasma signatures in heavy-ion collisions.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.64876.v1/t1","@type":"Dataset","description":"Single differential production cross sections of prompt J/PSI mesons and of J/PSI from B decay as a function of transverse...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.64876.v1/t2","@type":"Dataset","description":"Single differential production cross sections of prompt J/PSI mesons and of J/PSI from B decay as a function of transverse...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.64876.v1/t3","@type":"Dataset","description":"Single differential production cross sections of prompt J/PSI mesons and of J/PSI from B decay as a function of rapidity...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.64876.v1/t4","@type":"Dataset","description":"Single differential production cross sections of prompt J/PSI mesons and of J/PSI from B decay as a function of rapidity...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.64876.v1/t5","@type":"Dataset","description":"Double differential production cross sections of prompt J/PSI mesons as a function of transverse momentum and rapidity in the FORWARD...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.64876.v1/t6","@type":"Dataset","description":"Double differential production cross sections of J/PSI mesons from B decays as a function of transverse momentum and rapidity in...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.64876.v1/t7","@type":"Dataset","description":"The nuclear modification factor RpPB for PT < 14 GeV/c in the BACKWARD and FORWARD regions.","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.64876.v1/t8","@type":"Dataset","description":"The FORWARD/BACKWARD production ratio R(FB) as a function of rapidity for PT < 14 GeV/c.","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.64876.v1/t9","@type":"Dataset","description":"The FORWARD/BACKWARD production ratioo (R(FB) as a function of PT with |yrap|=2.5-4.0.","name":"Table 9"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1251899?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/64876"}],"inLanguage":"en","name":"Study of $J/\\psi$ production and cold nuclear matter effects in $p$Pb collisions","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1251899?version=1","version":1}
