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 ...

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 ...

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 ...

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 ...

The difference in the angular distributions between beauty quarks and antiquarks, referred to as the charge asymmetry, is measured for the first time in b¯b pair production at a hadron collider. The ...

During 2011 the LHCb experiment at CERN collected 1.0 fb−1 of s√=7~TeV pp collisions. Due to the large heavy quark production cross-sections, these data provide unprecedented samples of heavy flavoured ...

The kinematic dependences of the relative production rates, fΛ0b/fd, of Λ 0b baryons and B 0 mesons are measured using Λ 0b → Λ +c π − and B¯¯¯¯0 →D+π− decays. The measurements use proton-proton ...

A measurement of the inclusive Z → ττ cross-section in pp collisions at s√=7TeV is presented based on a dataset of 1.0 fb−1 collected by the LHCb detector. Candidates for Z → τ τ decays are identified ...

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 ...
