Studies of jet mass in dijet and W/Z plus jet events
(Springer Science+Business Media, 2013-05)
Invariant mass spectra for jets reconstructed using the anti-k(T) and Cambridge-Aachen algorithms are studied for different jet "grooming" techniques in data corresponding to an integrated luminosity of 5 fb(-1), recorded ...
Search in leptonic channels for heavy resonances decaying to long-lived neutral particles
(Springer Science+Business Media, 2013-02)
A search is performed for heavy resonances decaying to two long-lived massive neutral particles, each decaying to leptons. The experimental signature is a distinctive topology consisting of a pair of oppositely charged ...
Search for supersymmetry in events with b-quark jets and missing transverse energy in pp collisions at 7 TeV
(American Physical Society, 2012-10-01)
Results are presented from a search for physics beyond the standard model based on events with large missing transverse energy, at least three jets, and at least one, two, or three b-quark jets. The study is performed using ...
Measurement of the cross section and angular correlations for associated production of a Z boson with b hadrons in pp collisions at s√ = 7 TeV
(Elsevier, 2013-12)
A study of proton-proton collisions in which two b hadrons are produced in association with a Z boson is reported. The collisions were recorded at a centre-of-mass energy of 7 TeVwith the CMS detector at the LHC, for an ...
Studies of azimuthal dihadron correlations in ultra-central PbPb collisions at sNN−−−√ =2.76 TeV
(Springer Science+Business Media, 2014-02)
Azimuthal dihadron correlations of charged particles have been measured in PbPb collisions at sNN−−−√ = 2.76TeV by the CMS collaboration, using data from the 2011 LHC heavy-ion run. The data set includes a sample of ...
Search for the standard model Higgs boson produced in association with a W or a Z boson and decaying to bottom quarks
(American Physical Society, 2014-01-01)
A search for the standard model Higgs boson (H) decaying to bb¯ when produced in association with a weak vector boson (V) is reported for the following channels: W(μν)H, W(eν)H, W(τν)H, Z(μμ)H, Z(ee)H, and Z(νν)H. The ...
Search for pair production of first- and second-generation scalar leptoquarks in pp collisions at root s=7 TeV
(American Physical Society, 2012-09-01)
Results are presented from a search for the pair production of first- and second-generation scalar leptoquarks in proton-proton collisions at root s = 7 TeV. The data sample corresponds to an integrated luminosity of 5.0 ...
Search for massive resonances in dijet systems containing jets tagged as W or Z boson decays in pp collisions at root s=8 TeV
(Springer Science+Business Media, 2014-08)
A search is reported for massive resonances decaying into a quark and a vector boson (W or Z), or two vector bosons (WW, WZ, or ZZ). The analysis is performed on an inclusive sample of multijet events corresponding to an ...
Search for heavy resonances in the W/Z-tagged dijet mass spectrum in pp collisions at 7 TeV
(Elsevier, 2013-06-25)
A search has been made for massive resonances decaying into a quark and a vector boson, qW or qZ, or a pair of vector bosons, WW, WZ, or ZZ, where each vector boson decays to hadronic final states. This search is based on ...
Search for flavor-changing neutral currents in top-quark decays t -> Zq in pp collisions at root s=8 TeV
(American Physical Society, 2014-05-02)
A search for flavor-changing neutral currents in top-quark decays t -> Zq is performed in events produced from the decay chain (tt) over bar -> Zq + Wb, where both vector bosons decay leptonically, producing a final state ...
