Abstract

This article presents recent results of the Z boson production in the proton-lead collisions and the charmonium production in the ultra-peripheral lead-lead collisions at the LHC collected during 2013 to 2018 by the LHCb detector. The potential heavy ion programs in these topics are also discussed.

Highlights

  • The LHCb detector [1, 2] is a fully instrumented single-arm spectrometer in the forward region covering a pseudorapidity acceptance of 2 < η < 5, providing a high tracking momentum resolution down to very low transverse momentum and precise vertex reconstruction capability

  • The detector is originally designed for heavy-flavour measurements, precision tests of the standard model (SM), and searches for physics beyond the SM

  • As a young member of the LHC heavy ion program, the LHCb experiment provides the unique datasets for the heavy ion physics studies at LHC

Summary

Introduction

The LHCb detector [1, 2] is a fully instrumented single-arm spectrometer in the forward region covering a pseudorapidity acceptance of 2 < η < 5, providing a high tracking momentum resolution down to very low transverse momentum (pT) and precise vertex reconstruction capability. As a young member of the LHC heavy ion program, the LHCb experiment provides the unique datasets for the heavy ion physics studies at LHC. The heavy ion program at LHCb includes proton-lead (pPb), lead-lead (PbPb), and xenon-xenon (XeXe) collisions, together with fixed-target collisions of p or Pb with noble gases nuclei injected around the interaction point. We present recent results of the Z boson production in the proton-lead collisions [3, 4] and the charmonium production in the ultra-peripheral lead-lead collisions [5] at the LHC using datasets collected during 2013 to 2018 by the LHCb detector
