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 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 ...
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 ...
Search for heavy neutrinos and third-generation leptoquarks in hadronic states of two τ leptons and two jets in proton-proton collisions at √s = 13 TeV
(Springer Nature, 2019-03-26)
A search for new particles has been conducted using events with two high transverse momentum leptons that decay hadronically and at least two energetic jets. The analysis is performed using data from proton-proton collisions ...
Search for top quark partners with charge 5/3 in the same-sign dilepton and single-lepton final states in proton-proton collisions at s√=13 TeV
(Springer Nature, 2019-03-14)
A search for the pair production of heavy fermionic partners of the top quark with charge 5/3 (X-5/3) is performed in proton-proton collisions at a center-of-mass energy of 13 TeV with the CMS detector at the CERN LHC. The ...
