TeV for quarkonium rapidity |y| < 2.4. Differential cross sections and nuclear modification factors are reported as functions of y and transverse momentum pT, as well as collision centrality. For prompt J/ψ with relatively high pT (6.5 < pT < 30 GeV/c), a strong, centrality-dependent suppression is observed in PbPb collisions, compared to the yield in pp collisions scaled by the number of inelastic nucleon-nucleon collisions. In the same kinematic range, a suppression of non-prompt J/ψ, which is sensitive to the in-medium b-quark energy loss, is measured for the first time. Also the low-pT

Measurements of the pp → Wγγ and pp → Zγγ cross sections and limits on anomalous quartic gauge couplings at √s = 8 TeV

The Λb differential production cross section and the cross-section ratio σ(Λb)/σ(Λb) are measured as functions of transverse momentum pb T and rapidity |yΛb | in pp collisions at √ s = 7 TeV using data collected by the CMS experiment at the LHC. The measurements are based on Λb decays reconstructed in the exclusive final state J/ψΛ, with the subsequent decays J/ψ→ μ+μ− and Λ→ pπ, using a data sample corresponding to an integrated luminosity of 1.9 fb−1. The product σ(Λb)× B(Λb → J/ψΛ) versus pb T falls faster than that of b mesons. The measured value of σ(Λb)×B(Λb → J/ψΛ) for pb T > 10 GeV and |yΛb | < 2.0 is 1.16 ± 0.06 ± 0.12 nb, and the integrated σ(Λb)/σ(Λb) ratio is 1.02 ± 0.07 ± 0.09, where the uncertainties are statistical and systematic, respectively.
