含粲分子的态:来自真空与有限温度分析的见解

Molecular states with charm: insights from vacuum and finite-temperature analyses

Juan M. Torres-Rincon

AI总结:

本文基于重夸克自旋对称性的有效理论和幺正化方法,研究开粲与隐粲强子态的分子结构,重点分析$D_0^*(2300)$、$D_{s0}^*(2317)$、$X(3872)$和$X(4014)$,并探讨飞米测量和温度效应在确认其内部结构中的作用。

摘要:

这篇提交给SQM2024会议的论文涵盖了关于若干开粲和隐粲态内部结构的分子假说。采用包含重夸克自旋对称性的有效理论,并结合幺正化技术,已为支持这一解释提供了有力证据。在重-轻夸克扇区,我们讨论了$D_0^*(2300)$的双极点结构以及$D_{s0}^*(2317)$的产生机制。在隐粲扇区,我们重点关注奇异的$X(3872)$及其重夸克伙伴$X(4014)$。此外,我们强调了在$p+p$碰撞中进行飞米尺度测量对于确定这些态的性质的益处,以及温度在辨别其内部结构方面的潜在作用。

英文摘要:

This contribution to the SQM2024 conference covers the molecular hypothesis for the internal structure of some open and hidden charm states. The use of effective theories that incorporate heavy-quark spin symmetry, combined with unitarization techniques, has provided strong evidences supporting this interpretation. In the heavy-light sector, we discuss the double pole structure of the $D_0^*(2300)$ and the generation of the $D_{s0}^*(2317)$. In the hidden charm sector, we focus on the exotic $X(3872)$ and its heavy-quark partner, the $X(4014)$. Furthermore, we emphasize the benefits of femtoscopic measurements in $p+p$ collisions to establish the nature of these states, as well as the potential role of temperature to discern their internal structure.
