Description
We present a detailed study of momentum broadening for high-energy partons traversing the Quark--Gluon Plasma (QGP), extending the Gyulassy Levai Vitev (GLV) formalism to include both all-path-length (APL) and sub-eikonal corrections. Standard GLV calculations rely on the assumptions of large separation distances and large formation times, which are well justified in large nuclear systems but may break down in small systems such as pp and p/dA collisions, where characteristic path lengths and coherence scales become comparable.
Working to first order in the opacity expansion, we derive analytic expressions for the transverse momentum broadening distribution that systematically relaxes these approximations. The all-path-length correction emerges after we relax the large separation distance approximation.
For the sub-eikonal and combined sub-eikonal APL corrections, we introduce an updated set of kinematics that goes beyond the strict eikonal approximation.
Our results demonstrate that both all-path-length and sub-eikonal corrections can be phenomenologically important in small collision systems and provide a more controlled framework for studying jet medium interactions beyond the standard GLV approximations.
