“…[6]. The 10%-40% results are not very different from those obtained with minimum bias events shown previ- ously [5], but now are shown as a function of centrality in the middle panel for protons and antiprotons. In the lower panel the relative difference normalized by v norm 2 , the proton elliptic flow at p T = 1.5 GeV/c, shows a clear centrality dependence with a bigger effect for the more central collisions.…”

Elliptic flow (v2) values for identified particles at midrapidity in Au + Au collisions measured by the STAR experiment in the Beam Energy Scan at the Relativistic Heavy Ion Collider at √ sNN = 7.7-62.4 GeV are presented for three centrality classes. The centrality dependence and the data at √ sNN = 14.5 GeV are new. Except at the lowest beam energies we observe a similar relative v2 baryon-meson splitting for all centrality classes which is in agreement within 15% with the numberof-constituent quark scaling. The larger v2 for most particles relative to antiparticles, already observed for minimum bias collisions, shows a clear centrality dependence, with the largest difference for the most central collisions. Also, the results are compared with A Multiphase Transport Model and fit with a Blast Wave model.

After a cut on the event vertex along the beam direction of ±70 cm and a cut on the event vertex radial displacement from the mean of 1 cm, there were 17.5 M minimum-bias events available for data analysis.…”

“…impact parameter b < 2 fm) AMPT events with a partonparton scattering cross section σ = 1.5 mb for each system at √ s N N = 200 GeV. There are numerous publications utilizing the AMPT model to describe A + A collisions at RHIC, quoting a full range of input cross section values ranging from σ = 1.5 mb up to σ = 10 mb [15,28,29]. For this study, we have chosen the smallest value from this range to understand how a minimum parton scattering stage contributes to collective motion in these small systems.…”

Recent data from p+p and p+Pb collisions at the Large Hadron Collider (LHC), and d+Au and 3 He+Au collisions at the Relativistic Heavy Ion Collider (RHIC) reveal patterns that-when observed in the collision of heavy nuclei-are commonly interpreted as indicators of a locally equilibrated system in collective motion. The comparison of these data sets, including the forthcoming results from p+Au and p+Al collisions at RHIC, will help to elucidate the geometric dependence of such patterns. It has recently been shown that A-Multi-Phase-Transport-Model (AMPT) can describe some of these features in LHC data with a parton-parton scattering cross section comparable to that required to describe A + A data. In this paper, we extend these studies by incorporating a full wave function description of the 3 He nucleus to calculate elliptical and triangular anisotropy moments v2 and v3 for p+Au, d+Au and 3 He+Au collisions at the RHIC top energy of 200 GeV. We find reasonable agreement with the measured v2 in d+Au and 3 He+Au and v3 in 3 He+Au for transverse momentum (pT ) < ∼ 1 GeV/c, but underestimate these measurements for higher values of pT . We predict a pattern of coefficients (v2, v3) for p+Au, dominated by differences in the number of induced local hot spots (i.e. one, two, or three) arising from intrinsic geometry. Additionally, we examine how this substantial azimuthal anisotropy accrues during each individual evolutionary phase of the collision in the AMPT model. The possibility of a simultaneous description of RHICand LHC-energy data, the suite of different geometries, and high multiplicity p+p data is an exciting possibility for understanding the underlying physics in these systems.

“…Measurements of particle yields and kinematic distributions in electron-positron (e − +e + ), electron-proton (e ± +p), proton-proton (p(p)+p), proton-nucleus (p+A) and nucleus-nucleus (A+A(B)) collisions are essential for characterizing their global properties and to develop a good understanding of the mechanism(s) for particle production [1][2][3][4][5][6][7][8][9]. The p+p measurements also provide crucial reference data for studies of nuclear-medium effects in A+A(B) and p+A collisions, as well as improved constraints to differentiate between particle production models and to fine-tune event generators.…”

Scaling Properties of the Mean Multiplicity and Pseudorapidity Density in e−+e+, e±+p, p( p ¯ )+p, p+A and A+A(B) Collisions

et al. 2018

View full text Add to dashboard Cite

The charged-particle pseudorapidity density (dN ch /dη) for p(p)+p, p+A and A+A(B) collisions and the mean multiplicity N ch for e − +e + , e ± +p, and p(p)+p collisions are studied for a wide range of beam energies ( √ s). Characteristic scaling patterns are observed for both dN ch /dη and N ch , consistent with a thermal particle production mechanism for the bulk of the soft particles created in all of these systems. The scaling patterns found also validate an essential role for quark participants in these collisions. The measured values for dN ch /dη and N ch are observed to factorize into contributions that depend on log( √ s) and the number of nucleon or quark participant pairs N pp . The quantification of these contributions gives expressions that serve to systematize dN ch /dη and N ch measurements spanning nearly 4 orders of magnitude in √ s and to predict their values as a function of √ s and N pp .
