## Contribution

It introduces a lattice-based approach to measure the h_1 structure function, offering novel data on quark spin and relativistic dynamics.

## Key findings

- Measurement of the h_1 structure function from lattice QCD
- Insights into valence quark spin contributions
- Information on quark relativistic effects

## Abstract

We report on measurements of the h_1 structure function, relevant to calculating cross-sections for the Drell-Yan process. This is a quantity which can not be measured in Deep Inelastic Scattering, it gives additional information on the spin carried by the valence quarks, as well as insights on how relativistic the quarks are.
