The production yields of $\\Upsilon (1S)$, $\\Upsilon (2S)$, and $\\Upsilon (3S)$ quarkonium states are measured through their decays into muon pairs in the CMS detector, in PbPb and pp collisions at the centre-of-mass energy per nucleon pair of 2.76 TeV. The data correspond to integrated luminosities of 166 \u03bcb\u22121 and 5.4 pb\u22121 for PbPb and pp collisions, respectively. Differential production cross sections are reported as functions of $\\Upsilon$ rapidity y up to 2.4, and transverse momentum pT up to 20 GeV/c. A strong centrality-dependent suppression is observed in PbPb relative to pp collisions, by factors of up to $\\approx 2$ and 8, for the $\\Upsilon (1S)$ and $\\Upsilon (2S)$ states, respectively. No significant dependence of this suppression is observed as a function of y or pT. The $\\Upsilon (3S)$ state is not observed in PbPb collisions, which corresponds to a suppression for the centrality-integrated data by at least a factor of $\\approx 7$ at a 95% confidence level. The observed suppression is in agreement with theoretical scenarios modeling the sequential melting of quarkonium states in a quark gluon plasma.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.77220.v2/t1","@type":"Dataset","description":"Differential cross section for Y(1S) states as a function of their transverse momentum and per unit of rapidity in pp...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.77220.v2/t2","@type":"Dataset","description":"Differential cross section for Y(2S) states as a function of their transverse momentum and per unit of rapidity in pp...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.77220.v2/t3","@type":"Dataset","description":"Differential cross section for Y(3S) states as a function of their transverse momentum and per unit of rapidity in pp...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.77220.v2/t4","@type":"Dataset","description":"Differential cross section for Y(1S) states as a function of their transverse momentum and per unit of rapidity in PbPb...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.77220.v2/t5","@type":"Dataset","description":"Differential cross section for Y(2S) states as a function of their transverse momentum and per unit of rapidity in PbPb...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.77220.v2/t6","@type":"Dataset","description":"Differential cross section for Y(1S) states as a function of their rapidity and integrated over transverse momentum in pp collisions....","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.77220.v2/t7","@type":"Dataset","description":"Differential cross section for Y(2S) states as a function of their rapidity and integrated over transverse momentum in pp collisions....","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.77220.v2/t8","@type":"Dataset","description":"Differential cross section for Y(3S) states as a function of their rapidity and integrated over transverse momentum in pp collisions....","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.77220.v2/t9","@type":"Dataset","description":"Differential cross section for Y(1S) states as a function of their rapidity and integrated over transverse momentum in PbPb collisions....","name":"Table 9"},{"@id":"https://doi.org/10.17182/hepdata.77220.v2/t10","@type":"Dataset","description":"Differential cross section for Y(2S) states as a function of their rapidity and integrated over transverse momentum in PbPb collisions....","name":"Table 10"},{"@id":"https://doi.org/10.17182/hepdata.77220.v2/t11","@type":"Dataset","description":"Nuclear modification factor for \u03a5(1S) states in PbPb collisions as a function of pT.
