The LHCb simulation application, Gauss, consists of two independent phases, the generation primary event and tracking particles produced in experimental setup. For program it is particularly important to model B meson decays: EvtGen code developed CLEO BABAR has been chosen customized for non-coherent production as occuring pp collisions at LHC. initial proton-proton collision provided by a different generator engine, currently PYTHIA 6 massive signal generic events. Beam gas events,...
The performance of the LHCb Muon system and its stability across full 2010 data taking with LHC running at ps = 7 TeV energy is studied. optimization detector setting time calibration performed first collisions delivered by described. Particle rates, measured for wide range luminosities beam operation conditions experienced during run, are compared values expected from simulation. space alignment detectors, chamber efficiency, resolution cluster size evaluated. found to be as specifications...

The performance of the muon identification in LHCb is extracted from data using muons and hadrons produced J/ψ → μ+μ−, Λ0 pπ− D⋆+→π+D0(K−π+) decays. procedure based on pattern hits chambers. A momentum dependent binary requirement used to reduce probability be misidentified as level 1%, keeping efficiency range 95-98%. As further refinement, a likelihood built for non-muon hypotheses. Adding this that provides total at 93%, hadron misidentification probabilities are below 0.6%.
Abstract Open charm production in proton–proton collisions represents an important tool to investigate some of the most fundamental aspects quantum chromodynamics, from partonic mechanisms heavy-quark process hadronisation. Over last decade, measurement cross sections mesons and baryons (pp) was at centre a wide experimental effort Large Hadron Collider. Thanks complementarity different experiments, hadrons measured over transverse momentum region rapidity ranges. In this paper, measurements...

A method is described which allows to deduce the dead-time of front-end electronics LHCb muon detector from a series measurements performed at different luminosities bunch-crossing rate 20 MHz. The measured values range ∼ 70 ns 100 ns. These results allow estimate performance future 40 MHz and higher luminosity.
The recent and ongoing studies in quarkonium physics at LHCb are reviewed future prospects given the field of physics.
The LHCb Muon system performance is presented using cosmic ray events collected in 2009. These allowed to test and optimize the detector configuration before LHC start. space time alignment measurement of chamber efficiency, resolution cluster size are described detail. results agreement with expected performance.
We present recent results from charmonium and open charm production at the LHCb experiment CERN, Geneva. concentrate on studies for measurement of cross section pp ->JPsi+X in its decay channel with two muons, showing agreement simulation data few key distributions. also show reconstructed modes D0->K-pi+, D0 K-pi+pi0, LambdaC+ -> p K-pi+ D+ ->Ks0 pi+ their prospects.
