U.S.-Slovak Physics Research on Hardron and Dilepton Production in High Energy Collisions

[9319091]这个由尤金俄勒冈大学的Rudolph Hwa博士和布拉迪斯拉发夸美纽斯大学的Jan Pisut博士组成的美国-斯洛伐克研究项目的主要目的是研究相对论性重离子碰撞中夸克-胶子等离子体的可能形成。在此过程中，研究人员将专注于描述预平衡热化过程，以了解：1)导致J粒子与Psi粒子异常比例的抑制机制；2)双轻子和多粒子的产生。结果有望提高我们对致密介质核物质强相互作用的理解。这个高能物理项目通过使美国和东欧的领先专家在共同感兴趣和能力强的领域结合互补的人才和集中研究资源，实现了推进科学的计划目标。

9319091 Hwa The primary purpose of this U.S.-Slovak research project between Dr. Rudolph Hwa of the University of Oregon, Eugene, and Dr. Jan Pisut of Comenius University, Bratislava, is to study the possible formation of quark-gluon plasmas in relativistic heavy- ion collisions. In doing so, the researchers will focus on describing the pre-equilibrium thermalization process in order to understand: 1) the suppression mechanism causing an anomalous ratio of J particles to Psi particles and 2) dilepton and multi- particle production. Results are expected to improve our understanding of strong interaction in dense media nuclear matter. This project in high energy physics fulfills the program objectives of advancing science by enabling leading experts in the U.S. and Eastern Europe to combine complementary talents and pool research resources in areas of strong mutual interest and competence.
