Measurement of the B± Meson Nuclear Modification Factor in Pb-Pb Collisions at sNN =5.02 TeV
The differential production cross sections of B± mesons are measured via the exclusive decay channels B±→J/ψK±→μ+μ-K± as a function of transverse momentum in pp and Pb-Pb collisions at a center-of-mass energy sNN=5.02 TeV ...
Search for supersymmetry in events with at least one photon, missing transverse momentum, and large transverse event activity in proton-proton collisions at √s=13 TeV
A search for physics beyond the standard model in final states with at least one photon, large transverse momentum imbalance, and large total transverse event activity is presented. Such topologies can be produced in ...
Observation of Top Quark Production in Proton-Nucleus Collisions
The first observation of top quark production in proton-nucleus collisions is reported using proton-lead data collected by the CMS experiment at the CERN LHC at a nucleon-nucleon center-of-mass energy of sNN=8.16 TeV. The ...
Principal-component analysis of two-particle azimuthal correlations in PbPb and pPb collisions at CMS
For the first time a principle-component analysis is used to separate out different orthogonal modes of the two-particle correlation matrix from heavy ion collisions. The analysis uses data from sNN=2.76TeV PbPb and ...
Measurement of the differential cross sections for the associated production of a W boson and jets in proton-proton collisions at s =13 TeV
A measurement of the differential cross sections for a W boson produced in association with jets in the muon decay channel is presented. The measurement is based on 13 TeV proton-proton collision data corresponding to an ...
Search for a heavy composite Majorana neutrino in the final state with two leptons and two quarks at s=13TeV
A search for physics beyond the standard model in the final state with two same-flavour leptons (electrons or muons) and two quarks produced in proton–proton collisions at s=13TeV is presented. The data were recorded by ...
