In this article, we consider the ratio of structure functions for heavy quark pair production at low values of . The importance of this ratio for charm and beauty pair production is examined according to the Hadron Electron Ring Accelerator (HERA) data. The behavior of these ratios is considered due to the hard pomeron behavior of the gluon distribution function. The results are in good agreement with the HERA data. Expanding this data to the range of new energies underscores the importance of these measurements for heavy quarks. The ratio of charm and beauty structure functions at the proposed Large Hadron electron Collider (LHeC) is considered as a function of invariant center-of-mass energy. For top pair production this ratio is extracted with known kinematics of the LHeC and Future Circular Collider electron-hadron (FCC-eh) colliders. Comparison of the results obtained for the ratio of top structure functions in LHeC and FCC-eh are proportional to the specified inelasticity range.

在本文中，我们考虑了在低值下重夸克对产生的结构函数比. 根据强子电子环加速器 (HERA) 数据检查了该比率对魅力和美丽配对产生的重要性。这些比率的行为被认为是由于胶子分布函数的硬波默伦行为。结果与 HERA 数据非常吻合。将这些数据扩展到新能源的范围，强调了这些测量对重夸克的重要性。所提出的大型强子电子对撞机（LHeC）的魅力和美丽结构函数的比率被认为是不变质心能量的函数。对于顶对生产，这个比率是使用 LHeC 和未来圆形对撞机电子-强子 (FCC-eh) 对撞机的已知运动学提取的。范围。
