论文摘要
使用软共线的有效理论，我们开发了横向摩肌依赖性分解形式，用于极化 - 普罗顿电子碰撞中的浓烈风味dijet产生。我们考虑了共线和喷气功能以及相关的进化方程中的重型风味质量校正。使用这种形式主义，我们为未来电子离子撞机的魅力和底部产生的Gluon Sivers不对称产生了预测。此外，我们将理论预测与有限的夸克质量进行比较。我们发现，重型质量效应可以对预测的不对称性进行相当大的校正。
Using Soft-Collinear Effective Theory, we develop the transverse-momentum-dependent factorization formalism for heavy flavor dijet production in polarized-proton-electron collisions. We consider heavy flavor mass corrections in the collinear-soft and jet functions, as well as the associated evolution equations. Using this formalism, we generate a prediction for the gluon Sivers asymmetry for charm and bottom dijet production at the future Electron-Ion Collider. Furthermore, we compare theoretical predictions with and without the inclusion of finite quark masses. We find that the heavy flavor mass effects can give sizable corrections to the predicted asymmetry.
