Top: Charged-particle yields for the different triggers normalized to the number of leading charged particles with p_{T} > 0.4 GeV/c in double-sided events, as a function of leading-track p_{T}. The track-triggered distributions are normalized by the number of leading tracks in regions not affected by the rapid rise of the trigger efficiency near threshold. Bottom: Ratios of the leading-track p_{T} distributions for the four different triggers. The stars indicate the ratio of the 12 GeV/c over the minimum-bias samples, the circles the 20 over the 12 GeV/c samples, and the squares the ratio of the 30 over the 20 GeV/c track-triggered spectra. | |
Figure 2A | Abbreviated Caption |
Examples of interpolations between measured charged-particle differential cross sections at different sqrt(s) for p_{T} values of 3 and 15 GeV/c. The second-order polynomial fits, performed in the plane of the log-log invariant production vs. sqrt(s), are shown by the solid lines. The open squares and circles, and the filled crosses represent interpolated cross section values at 5.02 TeV using different methods: p_{T}-based interpolation, x_{T}-based interpolation, and relative placement, respectively. The error bars on the interpolated points represent the uncertainties in the fit. | |
Figure 2B | Abbreviated Caption |
Examples of interpolations between measured charged-particle differential cross sections at different sqrt(s) for x_{T} values of 0.014 and 0.040. These x_{T} values correspond to p_{T} ~ 35 and 100 GeV/c at sqrt(s) = 5.02 TeV. The second-order polynomial fits, performed in the plane of the log-log invariant production vs. sqrt(s), are shown by the solid lines. The open squares and circles, and the filled crosses represent interpolated cross section values at 5.02 TeV using different methods: p_{T}-based interpolation, x_{T}-based interpolation, and relative placement, respectively. The error bars on the interpolated points represent the uncertainties in the fit. | |
Figure 3 | Abbreviated Caption |
Measured charged-particle transverse momentum spectra in pPb collisions at sqrt(s_{NN}) = 5.02 TeV for: |η_{CM}| < 1.0, 0.3 < ± η_{CM} < 0.8, 0.8 < ± η_{CM} < 1.3, 1.3 < ± η_{CM} < 1.8, and the interpolated pp reference spectrum in |η_{CM}| < 1.0, normalized to the number of double-sided events. Positive pseudorapidity values correspond to the proton beam direction. The spectra have been scaled by the quoted factors to provide better visibility. Bottom: Systematic uncertainties in the measured pPb and interpolated pp spectra, as a function of p_{T}. | |
Figure 4 | Abbreviated Caption |
Measured nuclear modification factor as a function of p_{T} for charged particles produced in |η_{CM}| < 1.0. The shaded band at unity and p_{T} ~ 0.6 represents the uncertainty in the Glauber calculation of <T_{pPb}>. The smaller uncertainty band around the data points shows the uncertainty from effects (combining spectra, track selection, and trigger efficiency) that are fully correlated in specific p_{T} regions. The total systematic uncertainties, dominated by uncertainty in the pp interpolation, are shown by the larger band. | |
Figure 5 | Abbreviated Caption |
Charged-particle nuclear modification factors measured by CMS in |η_{CM}| < 1 (filled circles), and by ALICE in |η_{CM}| < 0.3 (open squares), are compared to the NLO pQCD prediction of Ref. 51. The theoretical uncertainty is based on the EPS09 error sets. For the CMS measurement, the shaded band at unity and p_{T} ~ 0.6 represents the uncertainty in the Glauber calculation of <T_{pPb}>, the smaller uncertainty band around the data points shows the fully correlated uncertainties and the total systematic uncertainty is shown by the larger band. For the ALICE measurement, the total systematic uncertainties, excluding the normalization uncertainty of 6%, are shown with open boxes. | |
Figure 6 | Abbreviated Caption |
Charged-particle forward-backward yield asymmetry as a function of p_{T} for 0.3 < |η_{CM}| < 0.8 (top), 0.8 < |η_{CM}| < 1.3 (middle), and 1.3 < |η_{CM}| < 1.8 (bottom). The asymmetry is computed as the charged-particle yields in the direction of the Pb beam divided by those of the proton beam. The solid curves are NLO pQCD theoretical calculations including nPDFs modifications [51]. The theoretical uncertainty is based on the EPS09 error sets. |
