项目摘要

Possible existence of color superconducting phase in Quantum Chromo Dynamics at high density has been pointed out by Iwasaki based on BCS-like mean field approach. An enhanced fluctuation of scaler density near chiral restoration has been reexamined by Hatsuda and Kuni-hiro. They have discussed that present experimental data imply such precursory phenomena. A new experiment has been proposed to confirm them. Driving mechanism of chiral symme-try breaking has been studied by Oka abd Takagi based on instanton induced interaction and Beth-Salpeter equation. Through the studies, chiral symmetric nature of , baryon spectrum has been clarified. A new method to evaluate effeciive potential has been developed by In-agaki. Structure of QCD vacuum has been analyzed by Suzuki and Miyamura using lattice simulation. It is found that both chiral symmetry breaking and topological structure are kept in a abelian projected gauge field occupied by monopoles. Internal structure of hadrons has been studied by Kodaira and Saito in perturbative and nonperturbative treatments. In the former, higher order correction has been newly calculated. Noda and Biyajima have analized high energy collisions of hadrons and leptons . Characteristics of baryon productions and multiparticle productions have been clarified. Kato and Tanaka has extended automatic cal-culation of Feynman diagram extended for the processes including super symmetric particles. Phase transition under high curvature has been investigated by Muta and Inagaki. Finally, a workshop has been organized in the end of the 1998 to discuss and to summerize results of this research program.
Iwasaki基于BCS类平均场方法指出了高密度下量子染色体动力学中可能存在色超导相。Hatsuda和Kuni-hiro重新研究了手征恢复附近标量密度的增强波动。他们已经讨论过,目前的实验数据暗示着这种反常现象。一个新的实验已经被提出来证实它们。Oka abd Takagi基于瞬子诱导相互作用和Beth-Salpeter方程研究了手征对称性破缺的驱动机制。通过研究,阐明了重子谱的手征对称性。In-agaki开发了一种评估有效潜力的新方法。Suzuki和Miyamura用晶格模拟方法分析了QCD真空的结构。结果表明,在被单极子占据的阿贝尔投影规范场中,手征对称破缺和拓扑结构都保持不变。科代拉和齐藤用微扰和非微扰方法研究了强子的内部结构。在前者中,新计算了高阶校正。Noda和Biyajima分析了强子和轻子的高能碰撞。阐明了重子产生和多粒子产生的特征。Kato和Tanaka将费曼图的自动计算推广到包括超对称粒子的过程。穆塔和Inagaki研究了高曲率下的相变。最后,在1998年底组织了一个讲习班,讨论和总结这一研究方案的成果。
