Journal ArticleDOI

Performance of the CMS drift-tube chamber local trigger with cosmic rays

S. Chatrchyan, +2463 more
- 01 Dec 2010 - 
TL;DR: In this paper, the performance of the Local Trigger based on the drift-tube system of the CMS experiment has been studied using muons from cosmic ray events collected during the commissioning of the detector in 2008.
Journal ArticleDOI

Measurement of the production cross section for single top quarks in association with W bosons in proton-proton collisions at √s=13 TeV

Albert M. Sirunyan, +2376 more
- 18 May 2018 - 
TL;DR: In this paper, a measurement of the associated production of a single top quark and a W boson in proton-proton collisions at root s = 13 TeV by the CMS Collaboration at the CERN LHC is presented.
Journal ArticleDOI

Search for new physics in the monophoton final state in proton-proton collisions at √s = 13 TeV

Albert M. Sirunyan, +2285 more
- 11 Oct 2017 - 
TL;DR: In this article, a search is conducted for new physics in a final state containing a photon and missing transverse momentum in proton-proton collisions at root s = 13 TeV.
Journal ArticleDOI

Study of Jet Quenching with $Z+ext{jet}$ Correlations in Pb-Pb and $pp$ Collisions at ${\sqrt{s}}_{NN}=5.02ext{ }ext{ }\mathrm{TeV}$

Albert M. Sirunyan, +2236 more
- 01 Jan 2017 - 
TL;DR: The R_{jZ} is found to be smaller in Pb-Pb than in pp collisions, which suggests that in P b-Bb collisions a larger fraction of partons associated with the Z bosons fall below the 30 GeV/c p_{T}^{jet} threshold because they lose energy.
Journal ArticleDOI

Search for neutralinos in Z decays

M. Acciarri, +494 more
- 04 May 1995 - 
TL;DR: In this paper, an upper bound of a few times 10 −5 on the branching ratio Z → χχ′ and Z→ χ′χ> was given for the lightest neutralino with m χ less than 18 GeV.
