Measurement of charged particle multiplicities and densities in pp collisions at √s=7 TeV in the forward region
(Springer, 2014)
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 ...
Study of J/ψ production and cold nuclear matter effects in pPb collisions at √sNN = 5 TeV
(Springer, 2014)
The production of J/ψ mesons with rapidity 1.5 < y < 4.0 or −5.0 < y < −2.5 and transverse momentum p T < 14 GeV/c is studied with the LHCb detector in proton-lead collisions at a nucleon-nucleon centre-of-mass energy √sNN ...
Searches for Λ0b and Ξ0b decays to K0Spπ− and K0SpK− final states with first observation of the Λ0b→K0Spπ− decay
(Springer, 2014)
A search for previously unobserved decays of beauty baryons to the final states K0spπ- and K0 spK- is reported. The analysis is based on a data sample corresponding to an integrated luminosity of 1.0 fb- of pp collisions. ...
Search for CP violation using T-odd correlations in D 0 → K + K −π+π− decays
(Springer, 2014)
A search for CP violation using T-odd correlations is performed using the four-body D 0 → K + K −π+π− decay, selected from semileptonic B decays. The data sample corresponds to integrated luminosities of 1.0 fb−1 and 2.0 ...
