3	Charmonium in Hot Medium Zhao, Xingbo 2010 December 1900 (has links) We investigate charmonium production in the hot medium created by heavy-ion collisions by setting up a framework in which in-medium charmonium properties are constrained by thermal lattice QCD (lQCD) and subsequently implemented into kinetic approaches. A Boltzmann transport equation is employed to describe the time evolution of the charmonium phase space distribution with the loss and gain term accounting for charmonium dissociation and regeneration (from charm quarks), respectively. The momentum dependence of the charmonium dissociation rate is worked out. The dominant process for in-medium charmonium regeneration is found to be a 3-to-2 process. Its corresponding regeneration rates from different input charmquark momentum spectra are evaluated. Experimental data on J/[psi] production at CERN-SPS and BNL-RHIC are compared with our numerical results in terms of both rapidity-dependent inclusive yields and transverse momentum (pt) spectra. Within current uncertainties from (interpreting) lQCD data and from input charm-quark spectra the centrality dependence of J/[psi] production at SPS and RHIC (for both mid-and forward rapidity) is reasonably well reproduced. The J/[psi] pt data are shown to have a discriminating power for in-medium charmonium properties as inferred from different interpretations of lQCD results.

4	Event-by-event correlations between Lambda hyperon and the chiral magnetic effect observables in Au+Au collisions at 27 GeV from STAR Yicheng Feng (12468297) 28 April 2022 (has links) <p>Spin-orbit interactions cause a global polarization [P] of Lambda (anti-Lambda) hyperons with the vorticity (or total angular momentum) in the participant collision zone. The strong magnetic field mainly created by the spectator protons would split the Lambda and anti-Lambda global polarization [Delta P]. Quantum chromodynamics (QCD) predicts topological charge fluctuation in vacuum, resulting in a chirality imbalance, or parity violation in a local domain. This would give rise to an imbalanced left- and right-handed Lambda (anti-Lambda) [Delta n], as well as a charge separation along the magnetic field, referred to as the chiral magnetic effect (CME). The latter can be characterized by the parity-even [Delta gamma] and parity-odd [Delta a1] observables. While measurements of the individual [Delta P], [Delta gamma], and [Delta a1] have not led to affirmative conclusions on the CME or the magnetic field, correlations among these observables may reveal new insights. We report exploratory measurements of event-by-event correlations between [Delta P] and [Delta gamma], and between [Delta n] and [Delta a1] by the STAR experiment in Au+Au collisions at 27 GeV. No correlations have been observed beyond statistical fluctuations. Future endeavor would be to extract an upper limit from the data as well as to apply the correlation analysis to other data samples.</p> Particle Physics Nuclear Physics heavy ion collision chiral magnetic effect Lambda hyperon global polarization STAR Collaboration STAR detector correlation Kalman filter
