Study of $\psi (2S)$ production and cold nuclear matter effects in pPb collisions at $\sqrt{s_{NN}}=5\mathrm{TeV}$

LHCb collaboration, R. Aaij, C. Abellán Beteta +732

The production of $\psi (2S)$ mesons is studied in dimuon final states using proton-lead collision data collected by the LHCb detector. The data sample corresponds to an integrated lum…
