Measurement of J/ψ production in p–Pb collisions at √sNN = 8.16 TeV with ALICE — •Minjung Kim for the ALICE collaboration — Physikalisches Institut, Universität Heidelberg
The measurement of J/ψ production in p–Pb collisions is an essential probe to study possible cold-nuclear-matter effects as well as final state mechanisms, the J/ψ which can affect production. In ALICE (A Large Ion Collider Experiment), J/ψ production is measured at mid-rapidity via the dielectron decay channel and at forward rapidity via the dimuon decay channel. Especially, at mid-rapidity, the contribution of J/ψ from weak decays of beauty hadrons (non-prompt J/ψ), can be separately measured thanks to the excellent primary and secondary vertex resolution of the Inner Tracking System (ITS). In the recent data taking period (Run 2), using the electron trigger of the Transition Radiation Detector (TRD), an enriched data sample of high–pT electron candidates was collected.
In this presentation, we will show the status of the inclusive and non-prompt J/ψ measurements in p–Pb collisions at √sNN = 8.16 TeV recorded with the TRD electron trigger.
