Observation of the rare Bs0 →µ+µ− decay from the combined analysis of CMS and LHCb data

S. Luyckx, S. Ochesanu, R. Rougny, M. Van De Klundert et autres

Combined analysis of proton-proton collision data from the Large Hadron Collider at CERN by the CMS and LHCb collaborations leads to the observation of the extremely rare decay of the strange B meson into muons; the result is compatible with the standard …

Production of leading charged particles and leading charged-particle jets at small transverse momenta in $pp$ collisions at $\sqrt{s}=8 TeV$

V. Khachatryan, A. M. Sirunyan, A. Tumasyan, W. Adam et autres

The per-event yield of the highest transverse momentum charged particle and charged-particle jet, integrated above a given pminT threshold starting at pminT=0.8 and 1 GeV, respectively, is studied in pp collisions at $\sqrt{s}=8 TeV$. The particles and the jets are measured in …

This paper presents a measurement of the inclusive 3-jet production differential cross section at a proton-proton centre-of-mass energy of 7 TeV using data corresponding to an integrated luminosity of 5 fb(-1) collected with the CMS detector. The analysis is based on the …

Constraints on the pMSSM, AMSB model and on other models from the search for long-lived charged particles in proton-proton collisions at √s=8TeV

V. Khachatryan, A. M. Sirunyan, A. Tumasyan, W. Adam et autres

Stringent limits are set on the long-lived lepton-like sector of the phenomenological minimal supersymmetric standard model (pMSSM) and the anomaly-mediated super-symmetry breaking (AMSB) model. The limits are derived from the results presented in a recent search for long-lived charged particles in proton-proton …
