Higher-twist effect in inclusive electron-positron annihilation
Jing Zhao, Yongjie Deng, Tianbo Liu +1
We establish a comprehensive theoretical framework for the electron-positron single-inclusive annihilation (SIA) process that incorporates higher-twist contributions up to twist-4…

The Sivers asymmetry of vector meson production in semi-inclusive deep inelastic scattering
Yongjie Deng, Tianbo Liu, Ya-jin Zhou
The transverse single-spin asymmetry for production in semi-inclusive deep inelastic scattering was recently reported by the COMPASS Collaboration. Using the Sivers function…

Testing Lepton Flavor Universality at the Electron-Ion Collider
Yongjie Deng, Xu-Hui Jiang, Tianbo Liu +1
Measurements of transitions at colliders are highly motivated for testing lepton flavor universality (LFU), a cornerstone hypothesis of the Standard Model (SM…
