Elliptic flow of J/$ψ$ at forward rapidity in Pb-Pb collisions at 2.76 TeV with the ALICE experiment

We present the elliptic flow of inclusive J/$ψ$ measured in the $μ^{+}μ^{-}$ channel at forward rapidity ($2.5<y<4.0$), down to zero transverse momentum, in Pb-Pb collisions at $\sqrt{s_{_{\mathrm{NN}}}}=2.76$ TeV with the ALICE muon spectrometer. The $p_{\mathrm T}$ dependence of J/$ψ$ $v_2$ in non-central (20%-60%) Pb-Pb collisions at $\sqrt{s_{_{\mathrm{NN}}}}=2.76$ TeV is compared with existing measurements at RHIC and theoretical calculations. The centrality dependence of the $p_{\mathrm{T}}$-integrated elliptic flow, as well as the $p_{\mathrm{T}}$ dependence in several finer centrality classes is presented.

Identified Particle Production in d+Au and p+p collisions at RHIC

The BRAHMS experiment at RHIC has measured the transverse momentum spectra of charged pions, kaons and (anti-)protons over a wide range of rapidity in d+Au and p+p collisions at $\sqrt{s_{NN}}=200 $GeV. The nuclear modification factor $R_{dAu}$ at forward rapidities shows a clear suppression for $π^{+}$. The measured net-proton yields in p+p collisions are compared to PYTHIA and HIJING/B and seem to be better described by the latter.
