Narrow Results

We simulate proton–proton interactions to study densities and multiplicities of charged particles at center-of-mass energy, $\sqrt{s}=7$ TeV in the forward region and compare predictions with experimental findings of LHCb detector. We use different event generators: Sibyll2.3c, EPOS (1.99 and LHC tunes), and DPMJETIII for the simulations. The kinematic region for momentum $p>2\mathrm{\text{GeV}}/c$, transverse momentum $p_T>0.2\mathrm{\text{GeV}}/c$ and $2.0<\eta <4.8$ in pseudorapidity is kept same as in the LHCb experiment for forward region. Predictions of different models and experimental data are presented and compared as a function of transverse momentum and pseudorapidity.

LHCb is a dedicated detector for b physics at the LHC (Large Hadron Collider). In this paper we present a concise review of the detector design and performance together with the main physics goals and their relevance for a precise test of the Standard Model and search of New Physics beyond it.

Here, we report on the results and prospects of the LHCb experiment at CERN as well as the upgrades of the LHCb detector within the scope of heavy-ion physics. A particular attention will be given to the extension of the fixed-target program and to the performance of the detector in high-occupancy nucleus–nucleus collisions. The technical description will be followed by a discussion of the results and the prospects for heavy-ion physics in fixed-target and collider mode.

The LHCb Experiment is going to search for the contribution of New Physics by studying large statistics samples of b-hadron decays. The key components of the experimental setup are discussed, followed by the overall status of the detector construction. The expected sensitivity is given for a few key channels.

The LHCb experiment will perform high-precision measurements of CP violation parameters and rare phenomena in B meson decays. It requires an excellent track reconstruction efficiency, particle identification and the precise measurement of secondary vertex positions in LHC collisions. We will discuss the methodology for the global reconstruction of tracks, using the ensemble of tracking detectors arranged on both sides of the LHCb dipole magnet. Hardware features of the tracking detectors that affect the tracking strategy will be outlined. We will describe the design and performance of the track reconstruction algorithms.
