Identification of b-quark jets with the CMS experiment
(IOP Publishing, 2013-04)
At the Large Hadron Collider, the identification of jets originating from b quarks is important for searches for new physics and for measurements of standard model processes. A variety of algorithms has been developed by ...
Search for Pair Production of Third-Generation Leptoquarks and Top Squarks in pp Collisions at √s=7 TeV
(American Physical Society, 2013-02)
Results are presented from a search for the pair production of third-generation scalar and vector leptoquarks, as well as for top squarks in R-parity-violating supersymmetric models. In either scenario, the new, heavy ...
Measurement of associated production of vector bosons and top quark-antiquark pairs in pp collisions at sqrt[s]=7 TeV
(American Physical Society, 2013-04)
The first measurement of vector-boson production associated with a top quark-antiquark pair in proton-proton collisions at √s=7 TeV is presented. The results are based on a data set corresponding to an integrated luminosity ...
Search for excited leptons in pp collisions at √s = 7 TeV
(Elsevier, 2013-02)
Results are presented of a search for compositeness in electrons and muons using a data sample of pp collisions at a center-of-mass energy √s = 7 TeV collected with the CMS detector at the LHC and corresponding to an ...
Measurement of the ZZ production cross section and search for anomalous couplings in 2ℓ2ℓ′ final states in pp collisions at √s = 7 TeV
(Springer Berlin Heidelberg, 2013-01)
A measurement is presented of the ZZ production cross section in the ZZ -> 2l2l' decay mode with l = e, μ and l' = e, μ, τ in proton-proton collisions at root √s = 7 TeV with the CMS experiment at the LHC. Results are based ...
Jet and underlying event properties as a function of charged-particle multiplicity in proton–proton collisions at √s= 7 TeV
(Springer-Verlag, 2013-12)
Characteristics of multi-particle production in proton-proton collisions at √s = 7 TeV are studied as a function of the charged-particle multiplicity, N ch . The produced particles are separated into two classes: those ...
Measurement of the W[superscript +]W[superscript −] √ and ZZ production cross sections in pp collisions at √s = 8 TeV
(Elsevier BV, 2013-03)
The W[superscript +]W[superscript −] and ZZ production cross sections are measured in proton-proton collisions at √s=8TeV with the CMS experiment at the LHC in data samples corresponding to an integrated luminosity of up ...
Determination of the top-quark pole mass and strong coupling constant from the t[bar over t] production cross section in pp collisions at √s = 7 TeV
(Elsevier, 2013-12)
The inclusive cross section for top-quark pair production measured by the CMS experiment in proton–proton collisions at a center-of-mass energy of 7 TeV is compared to the QCD prediction at next-to-next-to-leading order ...
Energy calibration and resolution of the CMS electromagnetic calorimeter in pp collisions at √s = 7 TeV
(IOP Publishing, 2013-09)
The energy calibration and resolution of the electromagnetic calorimeter (ECAL) of the CMS detector have been determined using proton-proton collision data from LHC operation in 2010 and 2011 at a centre-of-mass energy of ...
Search for supersymmetry in final states with missing transverse energy and 0, 1, 2, or ≥3 b-quark jets in 7 TeV pp collisions using the variable α T
(Springer-Verlag, 2013-01)
A search for supersymmetry in final states with jets and missing transverse energy is performed in pp collisions at a centre-of-mass energy of √s = 7 TeV. The data sample corresponds to an integrated luminosity of 4.98 ...
