Production of inclusive ${\rm Y}$(1S) and ${\rm Y}$(2S) in p-Pb collisions at $\sqrt{{\mathbf{s}}_{\mathrm{NN}}}=5.02$ TeV

Abstract

We report on the production of inclusive ${\rm Y}$(1S) and ${\rm Y}$(2S) in p-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV at the LHC. The measurement is performed with the ALICE detector at backward ($-4.46<y_{\mathrm{cms}}<-2.96$) and forward ($2.03<y_{\mathrm{cms}}<3.53$) rapidity down to zero transverse momentum. The production cross sections of the ${\rm Y}$(1S) and ${\rm Y}$(2S) are presented, as well as the nuclear modification factor and the ratio of the forward to backward yields of ${\rm Y}$(1S). A suppression of the inclusive ${\rm Y}$(1S) yield in p-Pb collisions with respect to the yield from pp collisions scaled by the number of binary nucleon-nucleon collisions is observed at forward rapidity but not at backward rapidity. The results are compared to theoretical model calculations including nuclear shadowing or partonic energy loss effects.
