标题： New Predictions for Charmed and Bottom Baryons

摘要： 我回顾了最近提出的观点，即存在新的同位旋三重态重重子，其质量分别约为2380 MeV和5760 MeV。 这一预测是通过对已观测到的粲重子和底重子态应用重夸克自旋-味对称性和轻夸克$SU(3)$对称性得出的。 它还涉及对已观测态的自旋和宇称量子数的假设，这些假设与通常的看法不同。 发现这类态将意味着非相对论的组分夸克模型在重重子谱学方面的预测能力较差。 我根据新获得的数据更新了分析。 显示英文摘要

摘要： I review the recent proposal that there are new isotriplet heavy baryons with masses approximately 2380 MeV and 5760 MeV. This prediction follows from the application of heavy spin-flavor and light $SU(3)$ symmetries to the observed charmed and bottom baryon states. It also entails assumptions about the spin and parity quantum numbers of the observed states which are different than is commonly supposed. The discovery of such states would imply that the nonrelativistic constituent quark model is a poor predictor of heavy baryon spectroscopy. I update the analysis in light of new data which have become available.
