光前场论可能为核物理和粒子物理学的研究提供一个有前景的途径,但实际计算需要场论的塔姆-丹科夫截断。这种截断限制了强子场论中允许的虚拟介子的数量,或者量子色动力学描述的束缚态中允许的夸克和胶子的数量。分析了过去的Tamm-Dancoff 重整化问题并提出了解决方案。
Light-front field theory may provide a promising avenue of research for nuclear and particle physics, but a Tamm-Dancoff truncation of field theory is required for practical computations. Such a truncation limits the number of virtual mesons allowed in hadronic field theories, or the number of quarks and gluons allowed in bound states described by quantum chromodynamics. Past Tamm-Dancoff renormalization problems are analyzed and a solution is proposed.
