Search for supersymmetry in events with at least three electrons or muons, jets, and missing transverse momentum in proton-proton collisions at √s=13 TeV
(2018-02-01)
A search for new physics is carried out in events with at least three electrons or muons in any combination, jets, and missing transverse momentum. Results are based on the sample of proton-proton collision data produced ...
Measurement of Prompt D0 Meson Azimuthal Anisotropy in Pb-Pb Collisions at sNN =5.02 TeV
(2018-05-16)
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. ...
Search for a heavy composite Majorana neutrino in the final state with two leptons and two quarks at s=13TeV
(2017-12-10)
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 ...
