论文摘要
探索$ t_ {cc} $，$ p_ {cs} $和隐藏式的baryon-antibaryon州的半含量电源，包括$ s $ s $ s-Wave have hadronic分子的一对Charmed Hadrons。我们采用蒙特卡洛事件发生器毕达氏菌来产生强子对，然后将它们结合在一起以形成handronic分子。通过使用这种生产机制，估计在数量级的水平上估计半包含的电源量。我们的结果表明，可以在中国和美国（EICC）和美国（EIC）的拟议的电子离子煤矿（EIC）中生产较大数量的$ P_ {CS} $状态和$λ_C\barλ_c$分子。结果还表明，可以在EIC上搜索$ t_ {cc} $状态和其他隐藏的baryon-antibaryon状态。此外，托马斯·杰斐逊国家加速器设施的连续梁加速器设施的潜在24-GEV升级在寻找隐藏的降解型和Pentaquark国家的较高亮度中可以发挥重要作用。
The semi-inclusive electroproduction of exotic hadrons, including the $T_{cc}$, $P_{cs}$, and hidden-charm baryon-antibaryon states, is explored under the assumption that they are $S$-wave hadronic molecules of a pair of charmed hadrons. We employ the Monte Carlo event generator Pythia to produce the hadron pairs and then bind them together to form hadronic molecules. With the use of such a production mechanism, the semi-inclusive electroproduction rates are estimated at the order-of-magnitude level. Our results indicate that a larger number of $P_{cs}$ states and $Λ_c\barΛ_c$ molecules can be produced at the proposed electron-ion colliders in China (EicC) and in the US (EIC). The results also suggest that the $T_{cc}$ states and other hidden-charm baryon-antibaryon states can be searched for at EIC. Besides, the potential 24-GeV upgrade of the Continuous Beam Accelerator Facility at the Thomas Jefferson National Accelerator Facility can play an important role in the search for the hidden-charm tetraquark and pentaquark states due to its high luminosity.
