Contribution

It introduces a framework linking generalized parton distributions with Regge phenomenology to study transversity in exclusive processes.

Findings

Proposes using $$ electroproduction to access transversity distributions.

Establishes a connection between GPDs and Regge models.

Highlights potential to measure tensor charge.

Abstract

Exclusive $\pi^o$ electroproduction and related processes are suggested to investigate the chiral odd transversity distributions of quarks in the transversely polarized nucleon, $h_1(x)$, and its first moment, the tensor charge. The connection between a description based on partonic degrees of freedom, given in terms of generalized parton distributions, and Regge phenomenology is explored.
