预测由核子和P波粲介子组成的奇异分子态

Predicting exotic molecular states composed of nucleon and P-wave charmed meson

Rui Chen, Zhi-Feng Sun, Xiang Liu, S. M. Gerasyuta

摘要:

本文研究了在$T$双重态中核子与$P$波粲介子交换π介子的相互作用。计算表明,一个核子和一个在$T$双重态中含有$J^P=0^+$或$J^P=1^+$的$P$波粲介子可以形成束缚态.我们建议在$D_1(2420)N$和$D_2^*(2460)N$阈值附近实验寻找这些奇异分子态,其中Belle,LHCb和即将到来的Belle II具有发现它们的潜力。

英文摘要:

In this work, we study the interaction between a nucleon and a $P$-wave charmed meson in the $T$ doublet by exchanging a pion. Our calculations indicate that a nucleon and a $P$-wave charmed meson with $J^P=0^+$ or $J^P=1^+$ in the $T$ doublet can form bound states. We propose the experimental search for these exotic molecular states near the $D_1(2420)N$ and $D_2^*(2460)N$ thresholds, where Belle, LHCb and the forthcoming Belle II have the discovery potential for them.
