Abstract

Predictions for charged hadron, identified light hadron, quarkonium, photon, jet and gauge bosons in p+Pb collisions at sqrt s_NN = 5 TeV are compiled and compared. When test run data are available, they are compared to the model predictions.

  • Figure 1: Charged particle pseudorapidity distributions at $\sqrt{s_{_{NN}}} = 5.02$ TeV in the CM (left) and lab (right) frames. The rcBK (dashed cyan) result is from Ref. Albacete:2012xq. The band labeled Rezaeian (dot-dot-dash-dashed green with vertical bars outlining the uncertainty), described in Sec. \ref{['sec:amir_ch']}, is only shown in the center-of-mass frame. The band showing the IP-Sat result described in Sec. \ref{['sec:IPSat']} is outlined by the dot-dot-dash-dashed black curves. The $\mathtt{HIJING2.1}$ result without (NS, dot-dash-dash-dashed red) and with shadowing ($s_g = 0.28$, solid red) and the $\mathtt{HIJINGB\overline{B}2.0}$ result without (dot dashed magenta) and with shadowing (dotted magenta) are also shown. Finally, the $\mathtt{AMPT-def}$ (dot-dash-dash-dashed blue) and $\mathtt{AMPT-SM}$ (dot-dot-dot-dash-dash-dashed blue) are given. The ALICE results from Ref. ALICE_dndeta are given on the right-hand side. The systematic uncertainties are shown in blue, the statistical uncertainties are too small to be visible on the scale of the plot.
  • Figure 2: Charged particle pseudorapidity distributions in the center of mass frame for $p+p$, $p+$Pb minimum bias and six of the centrality bins defined in Table \ref{['table1']} as calculated in $\mathtt{AMPT}$.
  • Figure 3: Charged particle pseudorapidity distributions in the center of mass frame of $p+$Pb collisions at various centralities within the b-CGC saturation model. The $\sim 5$% theoretical uncertainties arising from fixing the overall normalization at RHIC are also shown. From Ref. Rezaeian:2012ye.
  • Figure 4: (Left) Charged particle $p_T$ distributions at $\sqrt{s_{_{NN}}} = 5.02$ TeV. The solid and dashed cyan curves outline the rcBK band calculated by Albacete et al.Albacete:2012xq. The magenta curves, calculated with $\mathtt{HIJINGB\overline{B}2.0}$ as described in Sec. \ref{['sec:Pop_ch']} are presented without (dot-dashed) and with (dotted) shadowing. The $\mathtt{AMPT}$ results, given by the dot-dash-dash-dashed (default) and dot-dot-dot-dashed (SM) blue curves, are described in Sec. \ref{['sec:AMPT_ch']}. (Right) The charged hadron $p_T$ distribution in $p+$Pb collisions with different $\mathtt{HIJING2.1}$ options, scaled by the indicated factors to separate the curves. The $p+p$ distribution is shown for comparison.
