# Deuteron helicity flip generalized parton distributions in a convolution model

## TL;DR

This paper explores the properties of helicity-flip generalized parton distributions in spin-1 hadrons, using a light cone convolution model to analyze deuteron helicity amplitudes and the impact of angular momentum.

## Contribution

It introduces a convolution model for analyzing deuteron helicity-flip GPDs and discusses the role of angular momentum in these distributions.

## Key findings

- Helicity-flip GPDs are characterized for spin-1 hadrons.
- Deuteron helicity amplitudes include quark helicity flip components.
- Angular momentum influences the structure of these GPDs.

## Abstract

We discuss the general properties of generalized parton distributions with helicity flip (transversity) for spin-1 hadrons in the leading twist case. Using a basic light cone convolution model, we show the deuteron helicity amplitudes containing quark helicity flip GPDs and comment on the role deuteron angular momentum plays in these.
