$\barΛ_c$和$Λ_c$能否形成具有明确$P$波的束缚强子分子？
Could $\barΛ_c$ and $Λ_c$ form bound hadronic molecule with explicit $P-wave$ ?
AI总结：
研究$\bar{\Lambda}_c\Lambda_c$重子态的明确$P$波，通过十二个内插流计算，发现其正负电荷共轭差异不大，$P$波质量高于阈值，不太可能形成束缚分子，还计算了相关态的极点留数。
AI中文摘要：
本文通过十二个内插流研究了$J^{PC}=0^{-\pm}$和$1^{-\pm}$的$\bar{\Lambda}_c\Lambda_c$重子态的明确$P$波。结果表明，所研究态的正负电荷共轭差异不大，电流协变导数中胶子对$P$波的贡献可忽略。$P$波$\bar{\Lambda}_c\Lambda_c$质量的数值结果远高于两个$\bar{\Lambda}_c$和$\Lambda_c$重子成分的阈值，$\bar{\Lambda}_c$和$\Lambda_c$不太可能形成具有明确$P$波的束缚分子。还计算了相关态的极点留数。
英文摘要：
In this article, the explicit $P-wave$ of the $\barΛ_cΛ_c$ dibaryon states with the $J^{PC}=0^{-\pm}$ and $1^{-\pm}$ are studied via twelve interpolated currents. Results show that the positive and negative charge conjugations for the studied states do not have too much difference, the contribution of the gluon from covariant derivative of the current with $P-wave$ could be neglected. The numerical results of the masses of the $P-wave$ $\barΛ_cΛ_c$ are high above the threshold of the two $\barΛ_c$ and $Λ_c$ baryon constituents, $\barΛ_c$ and $Λ_c$ are unlikely to form the bound molecules with explicit $P-wave$ . Pole residues of the related states are also calculated.
