Constraints on the χ c1 versus χ c2 polarizations in proton-proton collisions at √s = 8 TeV
(American Physical Society, 2020-04-24)
The polarizations of promptly produced chi(c1) and chi(c2) mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at root s = 8 TeV. The chi(c) states are reconstructed via ...
Search for light bosons in decays of the 125 GeV Higgs boson in proton-proton collisions at √s = 8 TeV
(Springer International Publishing, 2017-10-11)
A search is presented for decays beyond the standard model of the 125 GeV Higgs bosons to a pair of light bosons, based on models with extended scalar sectors. Light boson masses between 5 and 62.5 GeV are probed in final ...
Search for Higgs boson pair production in the bbττ final state in proton-proton collisions at √(s) = 8 TeV
(American Physical Society, 2017-10-20)
Results are presented from a search for production of Higgs boson pairs (HH) where one boson decays to a pair of b quarks and the other to a t lepton pair. This work is based on proton-proton collision data collected by ...
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 ...
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 ...
