Abstract
The LHCb detector at the LHC has a pseudorapidity coverage (2<η<5) which allows it to perform particle production measurements in a kinematic region where QCD models have large uncertainties. Selected analyses on particle production measurements in pp collisions are summarised in these proceedings. The energy flow has been measured separately for different event classes allowing to probe multi-parton interactions at large η. The measured prompt hadron ratios are important for hadronisation models, while the p‾/p ratio is a good observable to test models of baryon number transport. Charm production has been studied to determine cross-sections and production ratios. All measurements are compared to a variety of theory predictions.
Highlights
The LHCb experiment at the Large Hadron Collider is a dedicated experiment to study CP-violating processes and rare decays of hadrons containing beauty and charm quarks
The detector is a single-arm forward spectrometer [1] designed to efficiently detect the decay products of B-hadrons in a pseudorapidity range of approximately 2 < η < 5. This allows LHCb to make particle production measurements in a kinematic region which is less accessible to the general purpose detectors
The analyses presented in these proceedings are selected particle production measurements performed with data from proto√n-proton collisions at centreof-mass energies of s = 0.9 and 7 TeV
Summary
The LHCb experiment at the Large Hadron Collider is a dedicated experiment to study CP-violating processes and rare decays of hadrons containing beauty and charm quarks. The detector is a single-arm forward spectrometer [1] designed to efficiently detect the decay products of B-hadrons in a pseudorapidity range of approximately 2 < η < 5. This allows LHCb to make particle production measurements in a kinematic region which is less accessible to the general purpose detectors. The analyses presented in these proceedings are selected particle production measurements performed with data from proto√n-proton (pp) collisions at centreof-mass energies of s = 0.9 and 7 TeV. Important for the presented analyses is the tracking system, which is composed of a high precision silicon Vertex Locator (VELO) surrounding the interaction point and the main. Particle identification (PID) is performed by two Ring Imaging Cherenkov (RICH) detectors which allow separation of charged particles in a momentum range of 2 − 100 GeV/c
