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

Search for the decay B-s(0) -> (D)over-bar(0) f(0)(980)

Roel Aaij, +735 more
TL;DR: In this paper, a search for the branching fraction of B_s^0 \to \overline{D}^{0} f_{0}(980) = 3.1\,(3.4) \times 10^{-6}$ is performed using collision data recorded by the LHCb experiment during 2011 and 2012.
Journal ArticleDOI

Search for the Lambda(0)(b) -> Lambda eta ' and Lambda(0)(b) -> Lambda eta decays with the LHCb detector

Roel Aaij, +750 more
TL;DR: In this article, a search was performed for the as yet unobserved baryonic Lambda(0)(b) -> Lambda eta' and Lambda((b) − ε, ε)-decays with 3 fb(-1) of proton-proton collision data recorded by the LHCb experiment.
Journal ArticleDOI

Precision Measurement of CP Violation in B-S(0) -> J/Psi K+K- Decays

Roel Aaij, +757 more
TL;DR: In this paper, the time-dependent CP asymmetry in B-S(0)-(B) → J/Psi K+K- decays is measured using pp collision data, corresponding to an integrated luminosity of 3.0 fb(-1), collected with the LHCb detector at center of mass energies of 7 and 8 TeV.
Journal ArticleDOI

Differential branching fraction and angular analysis of Lambda(0)(b) -> Lambda mu(+)mu(-) decays

Roel Aaij, +727 more
TL;DR: In this paper, the authors measured the differential branching fraction of the rare decay Λ0b→Λ0μ+μ− is measured as a function of q2, the square of the dimuon invariant mass.
