Search for long-lived particles decaying to jet pairs
A search is presented for long-lived particles with a mass between 25 and 50 GeV/c2 and a lifetime between 1 and 200ps in a sample of proton–proton collisions at a centre-of-mass energy of s√=7 TeV, corresponding to an ...
Measurement of charged particle multiplicities and densities in pp collisions at √s=7 TeV in the forward region
Charged particle multiplicities are studied in proton–proton collisions in the forward region at a centre-of-mass energy of √s=7TeV with data collected by the LHCb detector. The forward spectrometer allows access to a ...
Measurement of Υ production in pp collisions at √s=2.76TeV
The production of Υ(1S), Υ(2S) and Υ(3S) mesons decaying into the dimuon final state is studied with the LHCb detector using a data sample corresponding to an integrated luminosity of 3.3pb−1 collected in proton–proton ...
