Based on data corresponding to an integrated luminosity of 0.37 fb−1 collected by the LHCb experiment in 2011, the following ratios of branching fractions are measured: $ B(B0→π+π−)/B(B0→K+π−)=0.262±0 ...

Measurements of b-hadron masses are performed with the exclusive decay modes B+ -> J/psi K+, B0 -> J/psi K*0, B0 -> J/psi K0S, B0_s -> J/psi phi and Lambda_b -> J/psi Lambda using an integrated luminosity ...

A search for direct CP violation in D0 -> h- h+ (where h=K or pi) is presented using data corresponding to an integrated luminosity of 1.0 fb^-1 collected in 2011 by LHCb in pp collisions at a centre-of-mass ...

First observations of the decays Λ0b→Λ+cD−(s) are reported using data corresponding to an integrated luminosity of 3  fb−1 collected at 7 and 8 TeV center-of-mass energies in proton-proton collisions ...

Decays of b hadrons into final states containing a Dº meson and a muon are used to measure the bb production cross-section in proton–proton collisions at a centre-of-mass energy of 7 TeV at the LHC. In ...

Searches for heavy Majorana neutrinos in B− decays in final states containing hadrons plus a μ−μ− pair have been performed using 0.41  fb−1 of data collected with the LHCb detector in proton-proton ...

Limits on the cross-section times branching fraction for neutral Higgs bosons, produced in pp collisions at s√=7 TeV, and decaying to two tau leptons with pseudorapidities between 2.0 and 4.5, are ...

Decays of b hadrons into final states containing a D0 meson and a muon are used to measure the bb production cross-section in proton–proton collisions at a centre-of-mass energy of 7 TeV at the LHC. In ...

High centre-of-mass energies available in proton-proton collisions at the LHC allow models describing charmonium production to be tested. We distinguish promptly produced charmonia from those originating ...
