论文摘要

我们通过应用颜色玻璃冷凝物有效理论来预测高能深度弹性散射中的重型夸克产量。我们证明,当计算在近代领先的订单准确性上以巨大的夸克执行精度执行时,在偶极图片中首次有可能使用扰动计算的质量中心能量演化,同时描述在小$ x_ \ nathrm {bj} $上同时描述光和重型夸克生产数据。我们此外还显示了重夸克横截面数据如何为小$ x_ \ mathrm {bj} $ Evolution方程的提取的非扰动初始条件提供其他强大约束。

We predict heavy quark production cross sections in Deep Inelastic Scattering at high energy by applying the Color Glass Condensate effective theory. We demonstrate that when the calculation is performed consistently at next-to-leading order accuracy with massive quarks it becomes possible, for the first time in the dipole picture with perturbatively calculated center-of-mass energy evolution, to simultaneously describe both light and heavy quark production data at small $x_\mathrm{Bj}$. We furthermore show how the heavy quark cross section data provides additional strong constraints on the extracted non-perturbative initial condition for the small-$x_\mathrm{Bj}$ evolution equations.
