A search for new phenomena in pp collisions at √s = 13 TEV in final states with missing transverse momentum and at least one jet using the α[subscript T] variable
(2017-05)
A search for new phenomena is performed in final states containing one or more jets and an imbalance in transverse momentum in pp collisions at a centre-of-mass energy of 13TeV. The analysed data sample, recorded with the ...
Search for same-sign top-quark pair production at √ s = 7 TeV and limits on flavour changing neutral currents in the top sector
(Springer Science and Business Media LLC, 2011)
An inclusive search for same-sign top-quark pair production in pp collisions at √s = 7TeV is performed using a data sample recorded with the CMS detector in 2010, corresponding to an integrated luminosity of 35 pb -1. This ...
Observation of Z decays to four leptons with the CMS detector at the LHC
(Springer Science and Business Media LLC, 2012)
The first observation of the Z boson decaying to four leptons in proton-proton collisions is presented. The analyzed data set corresponds to an integrated luminosity of 5.02 fb-1 at s=7 TeV collected by the CMS detector ...
Combined search for electroweak production of charginos and neutralinos in proton-proton collisions at √s = 13 TeV
(Springer International Publishing AG, 2018-03)
A statistical combination of several searches for the electroweak production of charginos and neutralinos is presented. All searches use proton-proton collision data at √s = 13 TeV, recorded with the CMS detector at the ...
Search for large extra dimensions in dimuon and dielectron events in pp collisions at √s = 7 TeV
(Elsevier, 2012-03)
Results are presented from a search for large, extra spatial dimensions in events with either two isolated muons or two isolated electrons. The data are from proton–proton interactions at √s = 7 TeV collected with the CMS ...
Search for Heavy Majorana Neutrinos in μ[superscript ±]μ[superscript ±] + just and e[superscript ±]e[superscript ±] + jets events in pp collisions at √s = 7 TeV
(Elsevier, 2012-09)
A search is performed for heavy Majorana neutrinos (N) using an event signature defined by two same-sign charged leptons of the same flavour and two jets. The data correspond to an integrated luminosity of 4.98 fb[superscript ...
Search for Stopped Gluinos in pp Collisions at root s=7 TeV
(American Physical Society, 2011-01)
The results of the first search for long-lived gluinos produced in 7 TeV pp collisions at the CERN Large Hadron Collider are presented. The search looks for evidence of long-lived particles that stop in the CMS detector ...
Search for New Physics in the Multijet and Missing Transverse Momentum Final State in Proton-Proton Collisions at √s=7 TeV
(American Physical Society, 2012-10)
A search for physics beyond the standard model is performed in events with at least three jets and large missing transverse momentum produced in proton-proton collisions at a center-of-mass energy of √s=7 TeV. No significant ...
Searches for new physics using the t[bar over t] invariant mass distribution in pp collisions at √s = 8 TeV
(American Physical Society, 2013-11)
Searches for anomalous top quark-antiquark production are presented, based on pp collisions at s√ = 8 TeV. The data, corresponding to an integrated luminosity of 19.7 fb[superscript −1], were collected with the CMS ...
System Size, Energy, and Centrality Dependence of Pseudorapidity Distributions of Charged Particles in Relativistic Heavy-Ion Collisions
(American Physical Society, 2008-04)
We present the first measurements of the pseudorapidity distribution of primary charged particles in Cu+Cu collisions as a function of collision centrality and energy, [sqrt]s[subscript NN]=22.4, 62.4, and 200 GeV, over a ...
