“…Combining with the AGS, SPS (at its BES), RHIC (at its BES), one can study the QCD phase diagram over an energy range from a few GeV to 200 GeV [1][2][3][4]. In particular, the Large Hadron Collider (LHC) has extended the energy range to a few TeV and even more than 10 TeV [9][10][11][12]. It is convenient for researchers to study the QCD phase transition further.…”

Energy Dependent Chemical Potentials of Light Particles and Quarks from Yield Ratios of Antiparticles to Particles in High Energy Collisions

2019

View full text Add to dashboard Cite

We collect the yields of negatively and positively charged pions (π − and π + ), negatively and positively charged kaons (K − and K + ), as well as anti-protons (p) and protons (p) produced in mid-rapidity interval (in most cases) in central gold-gold (Au-Au), central lead-lead (Pb-Pb), and inelastic or non-single-diffractive proton-proton (pp) collisions at different collision energies. The chemical potentials of light particles and quarks are extracted from the yield ratios, π − /π + , K − /K + , andp/p, of negative to positive particles over an energy range from a few GeV to more than 10 TeV. At a few GeV (∼ 4 GeV), the chemical potentials show and the yield ratios do not show different behaviors comparing with those at other energies, though the limiting values of the chemical potentials and the yield ratios at very high energy are zero and one respectively.

“…Measurements of vector meson photoproduction in coherent pp or nuclear collisions have been used as a way of determining the gluon densities in protons and nuclei. The correlation between the vector meson photoproduction cross sections and the gluon densities in the leading-order approximation also gives us a unique opportunity to test the gluon distribution function over a large range of Bjorken-x, especially the pp collisions at √ s NN = 7 TeV from the LHCb Collaboration [1,2]. For a long time, PDF set analyses have achieved α s next-leading-order and even next-to-next-leading-order results.…”

Coherent photoproduction of J/ψandϒmesons in pp and PbPb ultraperipheral collisions from dynamical gluon distributions

We present calculations of coherent photoproduction of vector mesons (J/Ψ and Υ) with leading-order parton distribution functions to check new kinds of corrections of the DGLAP equations and nuclear modifications. The input gluon distribution of the proton is the dynamical parton model from the DGLAP equations with GLR-MQ-ZRS (Gribov-Levin-Ryskin, Mueller-Qiu, Zhu-Ruan-Shen) modifications. From comparison between several other gluon distribution models, we find that the dynamical gluon distribution fits with the results of meson photoproduction experiments in the high energy region. The calculation of the differential cross sections using dynamical and other gluon distributions is compared with the experimental data from the HERA, ZEUS and LHCb Collaborations. Although there is little data for the rapidity distribution of vector meson photoproduction near zero rapidity, the dynamical gluon distribution works well with the data in the large rapidity region.
