Hidden Color and the $b_1$ structure function of the deuteron

TL;DR

This paper introduces a model for hidden-color six-quark configurations in the deuteron, explaining the $b_1$ structure function and aligning well with existing data, while making predictions for future experiments.

Contribution

A novel simple model for hidden-color six-quark states in the deuteron that accounts for the $b_1$ structure function and matches experimental data.

Findings

Substantial contributions to $b_1$ for $x>0.2$

Good agreement with Hermes data

Predictions for upcoming JLab measurements

Abstract

The $b_1$ structure function is an observable feature of a spin-1 system sensitive to non-nucleonic components of the target nuclear wave function. A simple model for hidden-color, six-quark configurations is proposed and found to give substantial contributions for values of $ x>0.2$. Good agreement with Hermes data is obtained. Predictions are made for an upcoming JLab experiment.
