This grant covers Experimental Elementary Particle Physics research by a group at the Pennsylvania State University in collaboration with other NSF and DOE supported scientists. The group will continue at the Brookhaven National Laboratory (BNL), its measurements of Color Transparency and Light Cone Structure in QCD Bound States. Quantum Chromodynamics, a candidate theory describing the interactions of quarks and leptons, predicts that protons scattering at large angles from a proton or neutron within a heavy nucleus should experience reduced final state interactions, i.e. transparency, with respect to the other nucleons in the same nucleus. The group further will develop plans to study related problems of spin transfer in collisions at the proposed heavy ion collider at BNL.

这项资助涵盖了宾夕法尼亚州立大学的一个小组与其他NSF和DOE支持的科学家合作进行的实验基本粒子物理研究。该小组将继续在布鲁克海文国家实验室（BNL）测量QCD束缚态的颜色透明度和光锥结构。量子色动力学是描述夸克和轻子相互作用的候选理论，它预测，质子从重核中的质子或中子以大角度散射时，相对于同一核中的其他核子，最终态相互作用应该减少，即透明度。该小组将进一步制定计划，研究在BNL拟议的重离子对撞机碰撞中自旋转移的相关问题。
