We calculate the one-loop corrections to dihadron production in deep inelastic scattering (DIS) at small $x$ using the color glass condensate formalism. We show that all UV and soft singularities cancel while the collinear divergences are absorbed into quark and antiquark-hadron fragmentation functions. Rapidity divergences lead to Jalilian-Marian, Iancu, McLerran, Weigert, Leonidov and Kovner evolution of dipoles and quadrupoles describing multiple scatterings of the quark antiquark dipole on the target proton/nucleus. The resulting cross section is finite and can be used for phenomenological studies of dihadron angular correlations at small $x$ in a future Electron-Ion Collider.

smallx 对 DIS 中双强子产生的单循环校正

我们计算了深度非弹性散射 (DIS) 中双强子产生的单环修正$X$采用彩色玻璃凝形式主义。我们表明，当共线发散被吸收到夸克和反夸克-强子碎裂函数中时，所有的 UV 和软奇异点都会抵消。快速分歧导致 Jalilian-Marian、Iancu、McLerran、Weigert、Leonidov 和 Kovner 演化偶极子和四极子，描述了夸克反夸克偶极子在目标质子/核上的多次散射。得到的横截面是有限的，可用于小范围内双强子角相关的唯象学研究$X$在未来的电子离子对撞机中。
