论文摘要
在本文中，我们分析了包括$ b $ quarks的重夸克尼亚对的光生启动，例如$ b_ {c}^{+} b_ {c}^{c}^{ - } $ - mesons或charmonium-bottomonium pairs。与Charmonia配对的生产相比，这些渠道仅从某些图表中获得贡献，因此可以更好地理解对不同生产机制的理论理解。与生产隐藏味的Quarkonia相反，对于$ b_ {c} $的产生 - 梅森对，对建议的机制中的内部量子数没有限制。使用彩色玻璃冷凝物方法，我们从数值上估算了即将到来的电子 - 普罗顿碰撞器的运动学和LHC超验证碰撞运动学的生产横截面。我们发现，$ j/ψ\，η_{c} $和$ b_ {c}^{+} b_ {c}^{ - } $ Meson Pairs的生产是Quarkonia Pair Production的研究最有前途的渠道。
In this paper we analyze the photoproduction of heavy quarkonia pairs which include $b$-quarks, such as $B_{c}^{+}B_{c}^{-}$-mesons or charmonium-bottomonium pairs. Compared to charmonia pair production, these channels get contributions only from some subsets of diagrams, and thus allow for a better theoretical understanding of different production mechanisms. In contrast to the production of hidden-flavor quarkonia, for the production of $B_{c}$-meson pairs there are no restrictions on internal quantum numbers in the suggested mechanisms. Using the Color Glass Condensate approach, we estimated numerically the production cross-sections in the kinematics of the forthcoming Electron-Proton collider and in the kinematics of ultraperipheral collisions at LHC. We found that the production of $J/ψ\,η_{c}$ and $B_{c}^{+}B_{c}^{-}$ meson pairs are the most promising channels for studies of quarkonia pair production.
