量子强子动力学（QHD）是一个把核多体问题描述为重子和介子的相对论系统的框架。动机是这样一种方法的实用性和重要性的基础上的本地，洛伦兹不变的拉格朗日密度。讨论了在可重整化和不可重整化的有效QHD模型中计算核物质和有限核的问题。有效的和可重正化的模型之间的连接，以及相对论平均场理论和更复杂的治疗。本文综述了QHD的最新研究成果，包括核结构、核内的电弱相互作用、相对论输运理论、极端条件下的核物质以及对圈图的评价。
Quantum hadrodynamics (QHD) is a framework for describing the nuclear many-body problem as a relativistic system of baryons and mesons. Motivation is given for the utility of such an approach and for the importance of basing it on a local, Lorentz-invariant lagrangian density. Calculations of nuclear matter and finite nuclei in both renormalizable and nonrenormalizable, effective QHD models are discussed. Connections are made between the effective and renormalizable models, as well as between relativistic mean-field theory and more sophisticated treatments. Recent work in QHD involving nuclear structure, electroweak interactions in nuclei, relativistic transport theory, nuclear matter under extreme conditions, and the evaluation of loop diagrams is reviewed.
