Search for long-lived neutral particles decaying to quark-antiquark pairs in proton-proton collisions at √s = 8 TeV
(American Physical Society, 2015-01)
A search is performed for long-lived massive neutral particles decaying to quark-antiquark pairs. The experimental signature is a distinctive topology of a pair of jets, originating at a secondary vertex. Events were ...
Measurement of pseudorapidity distributions of charged particles in proton–proton collisions at √s = 8 TeV by the CMS and TOTEM experiments
(Springer-Verlag, 2014-10)
Pseudorapidity ( η ) distributions of charged particles produced in proton–proton collisions at a centre-of-mass energy of 8 TeV are measured in the ranges |η|<2.2 and 5.3<|η|<6.4 covered by the CMS and TOTEM detectors, ...
Search for vectorlike charge 2/3T quarks in proton-proton collisions at √(s) = 8 TeV
(American Physical Society, 2016-01)
A search for fermionic top quark partners T of charge 2/3 is presented. The search is carried out in proton-proton collisions corresponding to an integrated luminosity of 19.7 fb[superscript −1] collected at a center-of-mass ...
Search for resonant t[bar over t] production in proton-proton collisions at √s = 8 TeV
(American Physical Society, 2016-01)
A search is performed for the production of heavy resonances decaying into top-antitop quark pairs in proton-proton collisions at √s = 8 TeV. Data used for the analyses were collected with the CMS detector and correspond ...
Evidence for Collective Multiparticle Correlations in p-Pb Collisions
(American Physical Society, 2015-06)
The second-order azimuthal anisotropy Fourier harmonics, v[subscript 2], are obtained in p−Pb and PbPb collisions over a wide pseudorapidity (η) range based on correlations among six or more charged particles. The p-Pb ...
Search for charge-asymmetric production of W' bosons in t[bar over t] + jet events from pp collisions at √s = 7 TeV
(Elsevier, 2012-09)
A search is presented for charge-asymmetric production of a W′ boson that has been proposed to accommodate the forward–backward asymmetry observed in the production of top–antitop quark pairs at the Tevatron. The new heavy ...
Inclusive Search for a Vector-Like T Quark with Charge 2/3 in pp Collisions at √s = 8 TeV
(Elsevier, 2014-01)
A search is performed for a massive new vector-like quark T, with charge 2/3, that is pair produced together with its antiparticle in proton–proton collisions. The data were collected by the CMS experiment at the Large ...
Measurement of differential cross sections for Higgs boson production in the diphoton decay channel in pp collisions at t √s = 8 TeV
(Springer-Verlag, 2016-01)
A measurement is presented of differential cross sections for Higgs boson (H) production in pp collisions at √s=8 TeV . The analysis exploits the H→γγ decay in data corresponding to an integrated luminosity of 19.7 ...
The performance of the CMS muon detector in proton-proton collisions at √s = 7 TeV at the LHC
(IOP Publishing, 2013-11)
The performance of all subsystems of the CMS muon detector has been studied by using a sample of proton-proton collision data at √s = 7 TeV collected at the LHC in 2010 that corresponds to an integrated luminosity of ...
Azimuthal correlations for inclusive 2-jet, 3-jet, and 4-jet events in pp collisions at √s= 13 TeV
(Springer Berlin Heidelberg, 2018-07)
Azimuthal correlations between the two jets with the largest transverse momenta p[subscript T] in inclusive 2-, 3-, and 4-jet events are presented for several regions of the leading jet p[subscript T] up to 4 TeV. For 3- ...
