Nuclear Modified Transverse Momentum Distributions and 3D Imaging in Nuclei

TL;DR

This paper presents the first global analysis of nuclear-modified transverse momentum distributions (TMDs), demonstrating that experimental data from multiple experiments can be described with a simple non-perturbative correction model, leading to the extraction of nuclear-modified TMDs.

Contribution

It introduces the first comprehensive model for nuclear modifications of TMDs and extracts these distributions from a wide range of experimental data.

Findings

Successful description of diverse experimental data with a simple model

First extraction of nuclear-modified TMDs

Evidence of nuclear effects in transverse momentum distributions

Abstract

In this proceeding, we review our recent work in which we performed the first global analysis of nuclear modified Transverse Momentum Distribution Functions (TMDs). We demonstrate for the first time that the global set of TMD experimental data from HERMES, E866, E772, RHIC, ATLAS, and CMS, can be described using a simple model which accounts for the nuclear modifications for the TMDs as a non-perturbative correction. Using this model, we extract the nuclear modified TMDs for the first time.
