On the Stability of Leading-Power Factorization under Photon Propagator Numerator Modifications
Cong Li
We study collinear factorization in strong electromagnetic backgrounds within SCET for a class of modifications where the photon propagator keeps the vacuum pole structure and $i\v…

Study the impact of polarized background fields on coupling constants in EIC and EicC
Cong Li, Jing Zhao
In the polarized background field, the coupling constant will be influenced. We quantify this effect and propose that it can be measured at the EIC and EicC through the Bethe-Heitl…
