Searches for new physics using the t(t)over-bar invariant mass distribution in pp collisions at root s=8 TeV
(American Physical Society, 2013-11-22)
Searches for anomalous top quark-antiquark production are presented, based on pp collisions at root s = 8 TeV. The data, corresponding to an integrated luminosity of 19.7 fb(-1), were collected with the CMS detector at the ...
Measurement of the electron charge asymmetry in inclusive w production in pp collisions at root s=7 TeV
(American Physical Society, 2012-09-14)
A measurement of the electron charge asymmetry in inclusive pp -> W + X -> ev + X production at root s = 7 TeV is presented based on data recorded by the CMS detector at the LHC and corresponding to an integrated luminosity ...
Search for supersymmetry in hadronic final states with missing transverse energy using the variables alpha(T) and b-quark multiplicity in pp collisions at root s=8 TeV
(Springer Science+Business Media, 2013-09)
An inclusive search for supersymmetric processes that produce final states with jets and missing transverse energy is performed in pp collisions at a centre-of-mass energy of 8 TeV. The data sample corresponds to an ...
Measurement of WZ and ZZ production in pp collisions at in final states with b-tagged jets
(Springer Science+Business Media, 2014-08)
Measurements are reported of the WZ and ZZ production cross sections in proton-proton collisions at in final states where one Z boson decays to b-tagged jets. The other gauge boson, either W or Z, is detected through its ...
Search for invisible decays of Higgs bosons in the vector boson fusion and associated ZH production modes
(Springer Science+Business Media, 2014-08)
A search for invisible decays of Higgs bosons is performed using the vector boson fusion and associated ZH production modes. In the ZH mode, the Z boson is required to decay to a pair of charged leptons or a bb quark pair. ...
Study of the dijet mass spectrum in pp -> W + jets events at root s=7 TeV
(American Physical Society, 2012-12-21)
We report an investigation of the invariant mass spectrum of the two jets with highest transverse momentum in pp -> W + 2-jet and W + 3-jet events to look for resonant enhancement. The data sample corresponds to an integrated ...
Measurements of the tt¯tt¯ production cross section in lepton+jets final states in pp collisions at 8 TeVTeV and ratio of 8 to 7 TeVTeV cross sections
(Springer International, 2017)
A measurement of the top quark pair production () cross section in proton-proton collisions at the centre-of-mass energy of 8 is presented using data collected with the CMS detector at the LHC, corresponding to an integrated ...
Evidence for light-by-light scattering in ultraperipheral PbPb collisions at √sNN = 5.02 TeV
(Elsevier, 2019-02)
Evidence for light-by-light (LbL) scattering, gamma gamma -> gamma gamma, in ultraperipheral PbPb collisions at a nucleon-nucleon center of-mass energy of 5.02 TeV is reported. LbL scattering processes are selected in ...
Search for vectorlike charge 2 /3 T quarks in proton-proton collisions at (s)=8 TeV
(American Physical Society, 2016-01-01)
A search for fermionic top quark partners T of charge 2/3 is presented. The search is carried out in proton-proton collisions corresponding to an integrated luminosity of 19.7 fb−1 collected at a center-of-mass energy of ...
Measurement of differential cross sections for Higgs boson production in the diphoton decay channel in pp collisions at √s = 8 TeV
(Springer International Publishing, 2016-01)
A measurement is presented of differential cross sections for Higgs boson (H) production in pp collisions at s√=8s=8 TeVTeV . The analysis exploits the H→γγH→γγ decay in data corresponding to an integrated luminosity ...
