U.S.-Hungary Theoretical and Experimental Physics Investigation of the Application of Perturbative QCD to RHIC Measurements

这个由哥伦比亚大学的Brian A.Cole和他的合作伙伴Eotvos大学的Gabor Papp领导的美国-匈牙利研究项目的目标是将微扰量子色动力学(PQCD)计算应用到布鲁克海文相对论重离子对撞机(RHIC)设施的实验数据中。这将通过召集一组具有实验和理论专业知识的美国和匈牙利物理学家来完成，以澄清与将pQCD应用于核碰撞研究相关的问题。他们的目标是产生可靠的基线计算，重离子数据可以用来测试新的实验特征。预计结果将扩大pQCD可以应用和测试的问题范围。成功的实验应该从高动量转移散射过程中产生基本的定量信息，并有助于我们理解夸克与物质的相互作用。这将引起天体物理学家、宇宙学家以及核物理界的兴趣。这一理论和重离子核科学项目通过使美国和中欧的专家能够结合互补的人才并在相互感兴趣和能力很强的领域共享研究资源，实现了促进科学知识的计划目标。更广泛的影响包括通过在匈牙利机构的工作将美国学生和博士后介绍给国际核物理界，以及他们直接参与该项目提高RHIC发现潜力的努力。

The goal of this U.S.-Hungarian research project headed by Brian A. Cole of Columbia University and his partner, Gabor Papp of Eotvos University, is to apply perturbative quantum chromodynamics (pQCD) calculations to data from experiments at the Brookhaven Relativistic Heavy Ion Collider (RHIC) facility. This will be accomplished by bringing together a team of U.S. and Hungarian physicists with experimental and theoretical expertise to clarify issues associated with the application of pQCD to the study of nuclear collisions. Their goal is to produce sound baseline calculations against which heavy-ion data can be tested for novel experimental signatures. Results are expected to extend the range of problems for which pQCD can be applied and tested. Success should produce fundamental quantitative information from high-momentum transfer scattering processes and contribute to our understanding of the interaction of quarks with matter. This will interest astrophysicists and cosmologists as well as the nuclear physics community. This project in theory and heavy ion nuclear science fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Central Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence. Broader impacts include the introduction of U.S. students and post docs to the international nuclear physics community through work at the Hungarian institution and their direct involvement in the project's efforts to improve the discovery potential of RHIC.
