Measurement of the tt¯ production cross section in the dilepton channel in pp collisions at √s = 8 TeV
(2014-02-05)
The top-antitop quark ( tt¯) production cross section is measured in proton-proton collisions at √s = 8 TeV with the CMS experiment at the LHC, using a data sample corresponding to an integrated luminosity of 5.3 fb−1. ...
Search for long-lived particles that decay into final states containing two electrons or two muons in proton-proton collisions at s =8TeV
(2015-03-18)
A search is performed for long-lived particles that decay into final states that include a pair of electrons or a pair of muons. The experimental signature is a distinctive topology consisting of a pair of charged leptons ...
Constraints on the Higgs boson width from off-shell production and decay to Z-boson pairs
(2014-09-07)
Constraints are presented on the total width of the recently discovered Higgs boson, ΓH, using its relative
on-shell and off-shell production and decay rates to a pair of Z bosons, where one Z boson decays
to an electron ...
Search for resonant pair production of Higgs bosons decaying to two bottom quark-antiquark pairs in proton-proton collisions at 8 TeV
(2015-10-07)
A model-independent search for a narrow resonance produced in proton-proton collisions at √s=8 TeV and decaying to a pair of 125 GeV Higgs bosons that in turn each decays into a bottom quark-antiquark pair is performed by ...
Search for supersymmetry in pp collisions at √s = 8 TeV in events with a single lepton, large jet multiplicity, and multiple b jets
(2014-04-18)
Results are reported from a search for supersymmetry in pp collisions at a center-of-mass energy of
8 TeV, based on events with a single isolated lepton (electron or muon) and multiple jets, at least
two of which are ...
Study of W boson production in pPb collisions at √sNN=5.02TeV
(2015-09-28)
The first study of W boson production in pPb collisions is presented, for bosons decaying
to a muon or electron, and a neutrino. The measurements are based on a data
sample corresponding to an integrated luminosity of ...
Search for massive resonances decaying into pairs of boosted bosons in semi-leptonic final states at √s = 8 TeV
(2014-08-29)
A search for new resonances decaying to WW, ZZ, or WZ is presented. Final states are considered in which one of the vector bosons decays leptonically and the other hadronically. Results are based on data corresponding to ...
Constraints on the spin-parity and anomalous HVV couplings of the Higgs boson in proton collisions at 7 and 8 TeV
(2015-07-13)
The study of the spin-parity and tensor structure of the interactions of the recently discovered Higgs boson is performed using the H to ZZ, Z gamma*, gamma* gamma* to 4 l, H to WW to l nu l nu, and H to gamma gamma decay ...
Measurement of the hadronic activity in events with a Z and two jets and extraction of the cross section for the electroweak production of a Z with two jets in pp collisions at √s = 7 TeV
(2013-10-10)
The first measurement of the electroweak production cross section of a Z boson with two jets (Zjj) in pp collisions at √s 7 TeV is presented, based on a data sample recorded by the CMS experiment at the LHC with an integrated ...
Identification techniques for highly boosted W bosons that decay into hadrons
(2014-12-02)
In searches for new physics in the energy regime of the LHC, it is becoming increasingly important to distinguish single-jet objects that originate from the merging of the decay products of W bosons produced with high ...
