Measurements of tt¯ cross sections in association with b jets and inclusive jets and their ratio using dilepton final states in pp collisions at s=13TeV
The cross sections for the production of tt¯bb¯ and tt¯jj events and their ratio σtt¯bb¯/σtt¯jj are measured using data corresponding to an integrated luminosity of 2.3 fb−1collected in pp collisions at s=13 TeV with the ...
Search for vectorlike light-flavor quark partners in proton-proton collisions at ffiffi s p = 8 TeV
A search is presented for heavy vectorlike quarks (VLQs) that couple only to light quarks in proton-proton collisions at s=8 TeV at the LHC. The data were collected by the CMS experiment during 2012 and correspond to an ...
Search for decays of stopped exotic long-lived particles produced in proton-proton collisions at √s=13 TeV
A search is presented for the decays of heavy exotic long-lived particles (LLPs) that are produced in proton-proton collisions at a center-of-mass energy of 13 TeV at the CERN LHC and come to rest in the CMS detector. Their ...
Evidence for the Higgs boson decay to a bottom quark–antiquark pair
A search for the standard model (SM) Higgs boson (H) decaying to bb‾ when produced in association with an electroweak vector boson is reported for the following processes: Z(νν)H, W(μν)H, W(eν)H, Z(μμ)H, and Z(ee)H. The ...
Erratum to: Measurements of the Z→4ℓ branching fraction, and constraints on anomalous triple gauge couplings at s=13TeV
Reference : “Phys. Lett. B 763, 280” should have been corrected into “Phys. Lett. B 763, 280 (2016)”.
Combined search for electroweak production of charginos and neutralinos in proton-proton collisions at √s=13 TeV
A statistical combination of several searches for the electroweak production of charginos and neutralinos is presented. All searches use proton-proton collision data at s=13 TeV, recorded with the CMS detector at the LHC ...
Measurement of associated Z + charm production in proton–proton collisions at √s=8TeV
A study of the associated production of a Z boson and a charm quark jet (Z + c), and a comparison to production with a b quark jet (Z + b), in p p collisions at a centre-of-mass energy of 8TeV are presented. The analysis ...
Measurements of differential cross sections of top quark pair production as a function of kinematic event variables in proton-proton collisions at √s = 13 TeV
Measurements of differential t t ¯ production cross sections are presented in the single-lepton decay channel, as a function of a number of kinematic event variables. The measurements are performed with proton-proton ...
Search for Higgsino pair production in p p collisions at s = 13 TeV in final states with large missing transverse momentum and two Higgs bosons decaying via H → b b
Results are reported from a search for new physics in 13 TeV proton-proton collisions in the final state with large missing transverse momentum and two Higgs bosons decaying via H→bb. The search uses a data sample accumulated ...
Constraints on the chiral magnetic effect using charge-dependent azimuthal correlations in pPb and PbPb collisions at the CERN Large Hadron Collider
Charge-dependent azimuthal correlations of same- and opposite-sign pairs with respect to the second- and third-order event planes have been measured in pPb collisions at sNN=8.16TeV and PbPb collisions at 5.02 TeV with the ...
