“…Both Eqs. (5) and (22) are obtained in the framework of statistical thermal model [34,[36][37][38][39] or related literature [17]. These two formulas are different methods, but they should be harmonious in description of particle chemical potential at the stage of chemical freeze-out which is earlier than the strong and weak decays.…”

The yield ratios of negatively to positively charged pions (π − /π + ), negatively to positively charged kaons (K − /K + ), and anti-protons to protons (p/p) produced in mid-rapidity interval in central gold-gold (Au-Au) collisions, central lead-lead (Pb-Pb) collisions, and inelastic (INEL) or non-single-diffractive (NSD) proton-proton (pp) collisions, as well as in forward rapidity region in INEL pp collisions are analyzed in the present work. Over an energy range from a few GeV to above 10 TeV, the chemical potentials of light flavor particles (pion, kaon, and proton) and quarks (up, down, and strange quarks) are extracted from the mentioned yield ratios in which the contributions of strong decay from high-mass resonance and weak decay from heavy flavor hadrons are removed. Most energy dependent chemical potentials show the maximum at about 4 GeV, while the energy dependent yield ratios do not show such an extremum.

“…At high temperature/density, a deconfined thermalised state of quarks and gluons called Quarkgluon plasma (QGP) has been predicated by lattice QCD based calculations [1,2]. Values of ratio of certain observable measured in heavy ion collisions, such as number of produced strange particles, production of J/ψ, to those measured in p + p collision are interpreted as signature of partonic medium formation in heavy ion collisions; e.g., enhancement of number of strange particles and suppression in number of J/ψ in collisions of heavy ion with respect to that of p + p are taken as signatures of QGP formation in relativistic heavy collisions [3][4][5][6][7][8][9][10][11]. Apart from taking values of such ratio as confirmation for creation of QGP in such collisions, they are also used in characterizing QGP as well as in verifying and constraining different theoretical models.…”

Glauber model for a small system using the anisotropic and inhomogeneous density profile of a proton

et al. 2020

Recent studies reveal that at high energies, collisions of small system like p + p give signatures similar to that widely observed in heavy ion collisions hinting towards a possibility of forming a medium with collective behaviour. With this motivation, in this work, we have used Glauber model, which is traditionally applied to heavy ion collisions, in small system using anisotropic and inhomogeneous density profile of proton and found that the proposed model reproduces the charged particle multiplicity distribution of p + p collisions at LHC energies very well. Collision geometric properties like mean impact parameter, mean number of binary collisions ( N coll ) and mean number of participants ( Npart ) at different multiplicities are determined. Having estimated N coll , we have calculated nuclear modification-like factor (Rpp) in p+p collisions. We also estimated eccentricity and elliptic flow as a function of charged particle multiplicity using linear response to initial geometry.

“…One of the most important phenomena observed in high-energy heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC) is the strong collective flow of final state charged hadrons [1][2][3][4][5]. This is developed, presumably, by fast expansion of the quark gluon plasma (QGP) created in those collisions [6,7].…”

Complications in the interpretation of the charge-asymmetry-dependent π flow for the chiral magnetic wave

The charge asymmetry (A ch ) dependence of the π − and π + elliptic flow difference, ∆v2(A ch ), has been regarded as a sensitive observable for the possible chiral magnetic wave (CMW) in relativistic heavy ion collisions. In this work, we first demonstrate that, due to non-flow backgrounds, the flow measurements by the Q-cumulant method using all charged particles as reference introduce a trivial linear term to ∆v2(A ch ). The trivial slope can be negative in the triangle flow difference ∆v3(A ch ) if the non-flow is dominated by back-to-back pairs. After eliminating the trivial term, we find that the non-flow between like-sign pairs gives rise to an additional positive slope to ∆v2(A ch ) because of the larger dilution effect to π + (π − ) at positive (negative) A ch . We further find that the competition between different π sources can introduce another non-trivial linear-A ch term due to their different multiplicity fluctuations and anisotropic flows. We then study the effect of neutral cluster (resonance) decays as a mechanism for local charge conservation on the slope parameter of ∆v2(A ch ). We find that the slope parameter is sensitive to the kinematics of those neutral clusters. Light resonances give positive slopes while heavy resonances give negative slopes. Local charge conservation from continuum cluster mass distribution can give a positive slope parameter comparable to experimental data. Our studies indicate that many non-CMW physics mechanisms can give rise to a A ch -dependent ∆v2(A ch ) and the interpretation of ∆v2(A ch ) in terms of the CMW is delicate.PACS numbers: 25.75.Gz, 25.75.Ld
