Description

In this work, we study the azimuthal anisotropy of the back-to-back lepton-jet production in polarized lepton-proton collisions. This process defines three azimuthal angles: $\phi _S$ of the transverse spin $\boldsymbol{S}_T$ of the incident proton, $\phi _q$ of the transverse momentum imbalance $\boldsymbol{q}_T$ between the lepton and the jet, and $\phi _J$ of the jet transverse momentum. In particular, we provide the theoretical origins for the dependencies on $\left({\phi _q - \phi _J}\right)$ from a factorization formalism derived within the SCET framework. In addition, we present the numerical results of polarized azimuthal anisotropy related to the Sivers and worm-gear functions at EIC kinematics, showing that the interplay among the three azimuthal angles can create intriguing pictures.
