Abstract
Proton-lead and lead-proton data taking during 2013 has allowed LHCb to expand its physics program to heavy ion physics. Results include the first forward measurement of Z production in proton-lead collisions as well as a measurement of the nuclear modification factor and forward-backward production of prompt and displaced J/$\psi$, $\psi$(2S) and $\Upsilon$. Angular particle correlations have also been measured for events of varying charged particle activity.
Highlights
Proton-lead and lead-proton data taking during 2013 has allowed LHCb to expand its physics program to heavy ion physics
Designed for b-physics, the LHCb detector is becoming a general purpose detector by carrying out an extensive heavy-ion program
Data collected in the forward configuration amounts to Lint = 1.1 nb−1 while in the backward configuration it amounts to Lint = 0.5 nb−1
Summary
Investigate at forward rapidity the long-range correlation on the near side (ie the so-called ridge [7]) which was already observed in proton-proton (pp), proton-lead (pPb) and lead-lead (PbPb) collisions at mid-rapidity
