Search for high-mass Zγ resonances in proton–proton collisions at √s= 8 and 13 TeV using jet substructure techniques
(Elsevier, 2017-09-10)
A search for massive resonances decaying to a Z boson and a photon is performed in events with a hadronically decaying Z boson candidate, separately in light-quark and b quark decay modes, identified using jet substructure ...
First lattice calculation of charmed hadrons' electromagnetic form factors
(IOP Publishing, 2014)
Electromagnetic form factors of D and D* mesons and Ξcc, Σc, Ωc and Ωcc baryons are calculated in 2+1 flavor lattice QCD. As a by product of this calculation electric/magnetic charge radii and magnetic moments are extracted. ...
Performance of reconstruction and identification of τ leptons decaying to hadrons and vτ in pp collisions at √s=13 TeV
(IOP Publishing, 2018-10)
The algorithm developed by the CMS Collaboration to reconstruct and identify tau leptons produced in proton-proton collisions at root s = 7 and 8 TeV, via their decays to hadrons and a neutrino, has been significantly ...
Bose-Einstein correlations of charged hadrons in proton-proton collisions at s√ = 13 TeV
(Springer Nature, 2020-03-03)
Bose-Einstein correlations of charged hadrons are measured over a broad multiplicity range, from a few particles up to about 250 reconstructed charged hadrons in proton-proton collisions at <mml:msqrt>s</mml:msqrt> = 13 ...
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 ...
Charged-particle angular correlations in XeXe collisions at √sNN = 5.44 TeV
(American Physical Society, 2019-10-03)
Azimuthal correlations of charged particles in xenon-xenon collisions at a center-of-mass energy per nucleon pair of root s(NN) = 5.44 TeV are studied. The data were collected by the CMS experiment at the LHC with a total ...
Observation of the Z → ψ ℓ + ℓ − decay in pp collisions at √s = 13 TeV
(American Physical Society, 2018-10-04)
This Letter presents the observation of the rare Z boson decay Z→ψ + -. Here, ψ represents contributions from direct J/ψ and ψ(2S)→J/ψX, + - is a pair of electrons or muons, and the J/ψ meson is detected via its decay to ...
Constraints on models of scalar and vector leptoquarks decaying to a quark and a neutrino at √s = 13 TeV
(American Physical Society, 2018-08-10)
The results of a previous search by the CMS Collaboration for squarks and gluinos are reinterpreted to constrain models of leptoquark (LQ) production. The search considers jets in association with a transverse momentum ...
Measurement of the muon charge asymmetry in inclusive pp -> W plus X production at root s=7 TeV and an improved determination of light parton distribution functions
(American Physical Society, 2014-08-01)
Measurements of the muon charge asymmetry in inclusive pp -> W + X production at root s = 7 TeV are presented. The data sample corresponds to an integrated luminosity of 4.7 fb(-1) recorded with the CMS detector at the ...
Measurement of the Λb cross section and the (Lambda)over-bar(b) to Λb ratio with J/ψΛ decays in pp collisions at root s=7 TeV
(Elsevier, 2012-08-14)
The Lambda b differential production cross section and the cross section ratio sigma((Lambda) over bar (b))/sigma(Lambda(b)) are measured as functions of transverse momentum p(T)(Lambda b) rapidity vertical bar y(Lambda ...
