Evidence for the 125 GeV Higgs boson decaying to a pair of τ leptons

S. Chatrchyan, +2283 more
- 20 Jan 2014 - 
TL;DR: In this paper, a search for a standard model Higgs boson decaying into a pair of tau leptons is performed using events recorded by the CMS experiment at the LHC in 2011 and 2012.
Journal ArticleDOI

Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at √s=8 Tev

S. Chatrchyan, +2275 more
- 19 Feb 2014 - 
TL;DR: In this paper, a search for new physics in multijet events with large missing transverse momentum produced in proton-proton collisions at 8 TeV using a data sample corresponding to an integrated luminosity of 19.5 inverse femtobarns collected with the CMS detector at the LHC.
Journal ArticleDOI

Search for the standard model Higgs boson produced in association with a W or a Z boson and decaying to bottom quarks

S. Chatrchyan, +2203 more
- 21 Jan 2014 - 
TL;DR: In this paper, a search for the standard model Higgs boson decaying to bb¯ when produced in association with a weak vector boson (V) is reported for the following channels: W(μν)H, W(eν), W(τν), H, Z(μμ), Z(ee, H, and Z(νν), where the search is performed in data samples corresponding to integrated luminosities of up to 5.1 inverse femtobarns at s√=7
Journal ArticleDOI

Measurement of Higgs boson production and properties in the WW decay channel with leptonic final states

S. Chatrchyan, +2301 more
TL;DR: In this article, a search for the standard model Higgs boson decaying to a W-boson pair at the LHC is reported, and an excess of events above background is observed.
Journal ArticleDOI

Measurement of the Bs0→μ+μ- branching fraction and search for B0→μ+μ- with the CMS experiment

S. Chatrchyan, +2208 more
- 18 Jul 2013 - 
TL;DR: An unbinned maximum-likelihood fit to the dimuon invariant mass distribution gives a branching fraction B(Bs(0)→μ+ μ-)=(3.0(-0.9)(+1.0))×10(-9), where the uncertainty includes both statistical and systematic contributions.
