Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC

S. Chatrchyan, +2863 more
- 17 Sep 2012 - 
TL;DR: In this paper, results from searches for the standard model Higgs boson in proton-proton collisions at 7 and 8 TeV in the CMS experiment at the LHC, using data samples corresponding to integrated luminosities of up to 5.8 standard deviations.
Journal ArticleDOI

The CMS experiment at the CERN LHC

S. Chatrchyan, +3175 more
TL;DR: The Compact Muon Solenoid (CMS) detector at the Large Hadron Collider (LHC) at CERN as mentioned in this paper was designed to study proton-proton (and lead-lead) collisions at a centre-of-mass energy of 14 TeV (5.5 TeV nucleon-nucleon) and at luminosities up to 10(34)cm(-2)s(-1)
Journal ArticleDOI

Aleph: a detector for electron-positron annihilations at Lep

D. Decamp, +474 more
TL;DR: This paper presents a solution to support strategic processes in a PSEE by providing a flexible guidance during process enactment and shows that supporting processes is more concerned with the flexibility of guidance offered during the process performance than with enforcement of a collection of predefined process models.
Journal ArticleDOI

Experimental J / ψ hadronic production from 150 to 280 GeV/c

TL;DR: In this paper, a detailed study of J/ψ hadronic production has been performed in a high statistics experiment (more than 1.5 106 Jψ observed in their dimuon decay mode) and data have been taken with incident π±,K±,p±, at 150, 200 and 280 GeV/c.
Journal ArticleDOI

Searches for new particles in $Z$ decays using the ALEPH detector

D. Decamp, +403 more
- 01 Jan 1992 - 
TL;DR: In this paper, a comprehensive set of mass and coupling limits are presented for a number of rare hadronic and leptonic decays at the e+e− collider at the LEP, and the searches performed by ALEPH for Higgs bosons, supersymmetric particles, and for evidence of compositeness are reviewed.
