Abstract
2003 年, 标量粲-奇异介子 D_s0^* (2317) 和轴矢粲-奇异介子 D_s1 (2460) 的发现拉开了含重夸克的奇特强子态研究热潮的序幕. 随后, 实验又报道了不含奇异夸克的标量和轴矢粲介子D_0^* (2300)和 D_1 (2430). 它们的发现带来了数个谜题, 引发了大量理论和实验研究. 近年来, 随着有效场论和格点量子色动力学对相关系统的研究, 以及 LHCb 实验对数个 B 介子三体衰变的精确测量, 这些谜题已经在很大程度上得到了自然的解答; D_s0^* (2317) 和 D_s1 (2460) 的衰变宽度是确定这些粲介子内部结构的重要物理量, 理论的定量预言正等待实验的验证. 本文将概述对这些正宇称粲介子内部结构研究的进展.
