Measurement of the Λb polarization and angular parameters in Λb → J=ψΛ decays from pp collisions at ffiffi s p = 7 and 8 TeV
An analysis of the bottom baryon decay Λb→J/ψ(→μ+μ-)Λ(→pπ-) is performed to measure the Λb polarization and three angular parameters in data from pp collisions at s=7 and 8 TeV, collected by the CMS experiment at the Large ...
Measurement of normalized differential tt¯ cross sections in the dilepton channel from pp collisions at s√=13 TeV
Normalized differential cross sections for top quark pair production are measured in the dilepton (e⁺e⁻, μ⁺μ⁻, and μ∓e±) decay channels in proton-proton collisions at a center-of-mass energy of 13 TeV. The measurements are ...
Measurement of Prompt D0 Meson Azimuthal Anisotropy in Pb-Pb Collisions at sNN =5.02 TeV
The prompt D0 meson azimuthal anisotropy coefficients, v2 and v3, are measured at midrapidity (|y|<1.0) in Pb-Pb collisions at a center-of-mass energy sNN=5.02 TeV per nucleon pair with data collected by the CMS experiment. ...
Nuclear modification factor of D⁰ mesons in PbPb collisions at √sNN = 5.02 TeV
The transverse momentum (pT) spectrum of prompt D⁰ mesons and their antiparticles has been measured via the hadronic decay channels D⁰→K⁻π⁺ and D‾⁰→K⁺π⁻ in pp and PbPb collisions at a centre-of-mass energy of 5.02 TeV per ...
