Electroweak production of two jets in association with a Z boson in proton–proton collisions at √s= 13 TeV
(2018)The European Physical Journal CA measurement of the electroweak (EW) production of two jets in association with a Z boson in proton-proton collisions at s√=13TeV is presented, based on data recorded in 2016 by the CMS experiment at the LHC corresponding to an integrated luminosity of 35.9fb--1. The measurement is performed in the ℓℓjj final state with ℓ including electrons and muons, and the jets j corresponding to the quarks produced in the hard interaction. The ...Journal Article -
Measurement of the weak mixing angle using the forward–backward asymmetry of Drell–Yan events in p p collisions at 8 TeV
(2018)The European Physical Journal CA measurement is presented of the effective leptonic weak mixing angle (sin2θℓeff) using the forward–backward asymmetry of Drell–Yan lepton pairs (μμ and e e) produced in proton–proton collisions at s√=8TeV at the CMS experiment of the LHC. The data correspond to integrated luminosities of 18.8 and 19.6fb−1 in the dimuon and dielectron channels, respectively, containing 8.2 million dimuon and 4.9 million dielectron events. With more events ...Journal Article -
Search for massive resonances decaying into WW, WZ, ZZ, qW, and qZ with dijet final states at root √s=13 TeV
(2018)Physical Review DResults are presented from a search in the dijet final state for new massive narrow resonances decaying to pairs of W and Z bosons or to a W/Z boson and a quark. Results are based on data recorded in proton-proton collisions at √s=13 TeV with the CMS detector at the CERN LHC. The data correspond to an integrated luminosity of 35.9 fb−1. The mass range investigated extends upwards from 1.2 TeV. No excess is observed above the estimated ...Journal Article -
Search for supersymmetry in events with one lepton and multiple jets exploiting the angular correlation between the lepton and the missing transverse momentum in proton–proton collisions at √s =13TeV
(2018)Physics Letters BResults are presented from a search for supersymmetry in events with a single electron or muon and hadronic jets. The data correspond to a sample of proton–proton collisions at √s =13TeV with an integrated luminosity of 35.9fb-1, recorded in 2016 by the CMS experiment. A number of exclusive search regions are defined according to the number of jets, the number of b -tagged jets, the scalar sum of the transverse momenta of the jets, and ...Journal Article -
Constraining Gluon Distributions in Nuclei Using Dijets in Proton-Proton and Proton-Lead Collisions at √sNN =5.02 TeV
(2018)Physical Review LettersThe pseudorapidity distributions of dijets as functions of their average transverse momentum (paveT) are measured in proton-lead (pPb) and proton-proton (pp) collisions. The data samples were collected by the CMS experiment at the CERN LHC, at a nucleon-nucleon center-of-mass energy of 5.02 TeV. A significant modification of the pPb spectra with respect to the pp spectra is observed in all paveT intervals investigated. The ratios of the ...Journal Article -
Search for decays of stopped exotic long-lived particles produced in proton-proton collisions at √s=13 TeV
(2018)Journal of High Energy PhysicsA 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 decays would be visible during periods of time well separated from proton-proton collisions. Two decay scenarios of stopped LLPs are explored: a hadronic decay detected in the calorimeter and a decay into muons detected ...Journal Article -
Combination of inclusive and differential t(t)over-bar charge asymmetry measurements using ATLAS and CMS data at √s=7 and 8 TeV
(2018)Journal of High Energy PhysicsThis paper presents combinations of inclusive and differential measurements of the charge asymmetry (AC) in top quark pair (tt¯) events with a lepton+jets signature by the ATLAS and CMS Collaborations, using data from LHC proton-proton collisions at centre-of-mass energies of 7 and 8 TeV. The data correspond to integrated luminosities of about 5 and 20 fb−1 for each experiment, respectively. The resulting combined LHC measurements of ...Journal Article -

(2018)Physical Review DA measurement of jet substructure observables is presented using t¯t events in the lepton+jets channel from proton-proton collisions at √s=13 TeV recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 35.9 fb−1. Multiple jet substructure observables are measured for jets identified as bottom, light-quark, and gluon jets, as well as for inclusive jets (no flavor information). The results are unfolded to ...Journal Article -
Evidence for the Higgs boson decay to a bottom quark–antiquark pair
(2018)Physics Letters BA search for the standard model (SM) Higgs boson (H) decaying to bb͞ 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.

Observation of Higgs Boson Decay to Bottom Quarks
(2018)Physical Review LettersThe observation of the standard model (SM) Higgs boson decay to a pair of bottom quarks is presented. The main contribution to this result is from processes in which Higgs bosons are produced in association with a W or Z boson (VH), and are searched for in final states including 0, 1, or 2 charged leptons and two identified bottom quark jets. The results from the measurement of these processes in a data sample recorded by the CMS experiment ...Journal Article
