Field Theoretic Models of Nuclear and Subnuclear Systems (Physics)

相对论核场理论正在被研究，作为将原子核描述为经典量子多体系统的另一种选择。特别的努力针对的是准确计算平均场方程的量子修正并在实验数据中识别这种修正的签名的问题。正确地将介子纳入量子流体动力学(QHD)的问题也是一个主要目标。QHD的基本成分被视为重子和介子。这个问题与量子修正的计算密切相关，它为探索几种非微扰方法提供了工具。这项研究旨在开发一种描述原子核的方法，它适当地结合了在高反应中发现的亚核子粒子和相互作用，并试图将核物理统一到量子色动力学的统一理论中。

Relativistic nuclear field theories are being studied as an alternative to the description of the nucleus as a classical quantum many-body system. Particular effort is being directed at the problem of accurately calculating quantum corrections to the mean field equations and identifying signatures of such corrections in experimental data. The problem of correctly incorporating the pion into quantum hadrodynamics (QHD), where the fundamental constituents are taken as baryons and mesons, is also a major objective. This problem is closely related to the calculation of quantum corrections, and it provides a vehicle for exploring several nonperturbative approaches. This research is directed toward the development of a description of the nucleus which properly incorporates subnucleonic particles and interactions discovered in high reactions and seeks to unify nuclear physics to the unifying theory of quantum chromodynamics.
