Probing color coherence effects in pp collisions at s√=7 TeV
(Springer-Verlag, 2014-06)
A study of color coherence effects in pp collisions at a center-of-mass energy of 7 TeV is presented. The data used in the analysis were collected in 2010 with the CMS detector at the LHC and correspond to an integrated ...
Studies of dijet transverse momentum balance and pseudorapidity distributions in pPb collisions at √s[subscript NN] = 5.02 TeV
(Springer-Verlag, 2014-07)
Dijet production has been measured in pPb collisions at a nucleon–nucleon centre-of-mass energy of 5.02 TeV . A data sample corresponding to an integrated luminosity of 35 nb[superscript −1] was collected using the Compact ...
Measurement of associated W + charm production in pp collisions at √s = 7 TeV
(Springer Berlin Heidelberg, 2014-02)
Measurements are presented of the associated production of a W boson and a charm-quark jet (W + c) in pp collisions at a center-of-mass energy of 7 TeV. The analysis is conducted with a data sample corresponding to a total ...
Measurement of the ratio B(t → Wb)/B(t → Wq) in pp collisions at √s = 8 TeV
(Elsevier BV, 2014-07)
The ratio of the top-quark branching fractions R=B(t→Wb)/B(t→Wq), where the denominator includes the sum over all down-type quarks (q=b,s,d), is measured in the t[¯ overt] dilepton final state with proton–proton collision ...
Measurement of the production cross section for a W boson and two b jets in pp collisions at √s = 7 TeV
(Elsevier, 2014-06)
The production cross section for a W boson and two b jets is measured using proton–proton collisions at √s = 7 TeV in a data sample collected with the CMS experiment at the LHC corresponding to an integrated luminosity of ...
Study of double parton scattering using W + 2-jet events in proton-proton collisions at √s = 7 TeV
(Springer-Verlag, 2014-03)
Double parton scattering is investigated in proton-proton collisions at √s = 7 TeV where the final state includes a W boson, which decays into a muon and a neutrino, and two jets. The data sample corresponds to an integrated ...
Observation of the Associated Production of a Single Top Quark and a W Boson in pp Collisions at √s = 8 TeV
(American Physical Society, 2014-06)
The first observation of the associated production of a single top quark and a W boson is presented. The analysis is based on a data set corresponding to an integrated luminosity of 12.2 fb[superscript −1] of proton-proton ...
Measurement of jet fragmentation in PbPb and pp collisions at √s[subscript NN] = 2.76 TeV
(American Physical Society, 2014-08)
The jet fragmentation function of inclusive jets with transverse momentum p[subscript T] above 100GeV/c in PbPb collisions has been measured using reconstructed charged particles with p[subscript T] above 1 GeV/c in a cone ...
Search for neutral MSSM Higgs bosons decaying to a pair of tau leptons in pp collisions
(Springer-Verlag Berlin Heidelberg, 2014-10)
A search for neutral Higgs bosons in the minimal supersymmetric extension of the standard model (MSSM) decaying to tau-lepton pairs in pp collisions is performed, using events recorded by the CMS experiment at the LHC. The ...
Identification techniques for highly boosted W bosons that decay into hadrons
(Springer-Verlag, 2014-12)
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 ...
