Abstract
The LHCb detector is a single-arm spectrometer fully instrumented in the forward rapidity at the LHC. In this contribution we introduce some of the most recent results in heavy ion collisions, the upgrades for LHC Run3 and the future perspectives of the heavy ion program from the LHCb experiment.
Highlights
The LHCb detector [1] is a single-arm forward spectrometer fully instrumented in the pseudorapidity range 2 < η < 5
The coverage in the forward rapidity region is complementary to other major experiments at the LHC, and allows unique access to Bjorken-x region ∼ 10−6 − 1[2,3,4] inside the nucleus
With the introduction of the SMOG (System for Measuring overlap with gas) in 2015, the LHCb detector is equipped with the unique capability to operate in fixed-target configuration and study beam-gas collisions at lower energies using noble gas targets injected inside the primary LHC vacuum
Summary
The LHCb detector [1] is a single-arm forward spectrometer fully instrumented in the pseudorapidity range 2 < η < 5. The production of prompt charged hadrons is measured with precision in pp and pPb collisions at 5.02 TeV [5]. Since the LHCb detector covers only one direction in rapidity, two beam configures of pPb collisions are used. In the pPb or forward configuration, the proton beam travels from the vertex detector VELO to the muon chambers. The calculation using nuclear PDFs [6] agrees with the forward data within large nPDF uncertainties, but does not reproduce the enhancement in the backward region. The χc and χc charmonium production in nuclear collisions at LHC energies is first measured by the LHCb with pPb collisions at 8.16 TeV [9].
