On the process dependent nuclear $k_\perp$ broadening effect

Understand

We study the process dependent nuclear $k_\perp$ broadening effect by employing the transverse momentum dependent(TMD) factorization approach in combination with the Mclerran-Venugopalan(MV) model.

• More specifically, we investigate how the parton transverse momentum distributions are affected by the process dependent gauge links in cold nuclear matter.
• In particular, our analysis also applies to the polarized cases including the nuclear quark Boer-Mulders function and the linearly polarized gluon distribution.
• Our main focus is on the nuclear TMDs at intermediate or large x.
