标题： Glueball Spectroscopy in a Relativistic Many-Body Approach to Hadron Structure

摘要： 基于量子色动力学（QCD）哈密顿量的库仑规范，提出了一种全面的相对论多体方法来研究强子结构。 我们的方法结合了标准的多体技术，使得这些近似可以系统地改进。 利用BCS变分法，动态手征对称性破缺自然出现，夸克和胶子都获得了组分质量。 胶球在价态和集体随机相位近似下被研究。 使用强耦合常数和弦张力的代表性值，计算得到的淬火胶子球质量与格点规范理论的结果惊人地一致。 显示英文摘要

摘要： A comprehensive, relativistic many-body approach to hadron structure is advanced based on the Coulomb gauge QCD Hamiltonian. Our method incorporates standard many-body techniques which render the approximations amenable to systematic improvement. Using BCS variational methods, dynamic chiral symmetry breaking naturally emerges and both quarks and gluons acquire constituent masses. Gluonia are studied both in the valence and in the collective, random phase approximations. Using representative values for the strong coupling constant and string tension, calculated quenched glueball masses are found to be in remarkable agreement with lattice gauge theory.
