论文摘要
在本文中,我们研究了强Quarkonia对的高能量专有的光生源,并以强耦合常数为$α_{S} $的领先顺序。在建议的机制中,夸克尼亚对以相反的电荷平等产生,并且主要是对立的横向动量。使用彩色玻璃冷凝物方法,我们从数值上估计了即将到来的电子普罗顿山脉的运动学中的生产横截面,以及超抛光碰撞中的质子离子船员。我们发现,横截面在计划实验的范围内,可以以合理的精度进行测量。所建议的机制的横截面明显大于相同的$ c $ parity Quarkonia对生产。
In this paper we study the high energy exclusive photoproduction of heavy quarkonia pairs in the leading order of the strong coupling constant $α_{s}$. In the suggested mechanism the quarkonia pairs are produced with opposite charge parities, and have predominantly oppositely directed transverse momenta. Using the Color Glass Condensate approach, we estimated numerically the production cross-sections in the kinematics of the forthcoming electron-proton colliders, as well as proton-ion colliders in ultraperipheral collisions. We found that the cross-sections are within the reach of planned experiments and can be measured with reasonable precision. The suggested mechanism has significantly larger cross-section than that of the same $C$-parity quarkonia pair production.
