Single and Double Pion Photoproduction off the Deuteron

TL;DR

This paper reports on high-statistics measurements of single and double pion photoproduction off deuterons, highlighting the influence of nuclear effects like Fermi motion and meson rescattering on the process.

Contribution

It presents new experimental data on pion photoproduction off the deuteron, emphasizing the role of nuclear effects beyond Fermi motion.

Findings

Preliminary results show significant nuclear effects.

Data suggests meson rescattering impacts pion production.

High-statistics measurements improve understanding of nuclear interactions.

Abstract

There is evidence that the photoproduction of single and double pions off bound nucleons inside a nucleus are not only affected by Fermi motion but also by other nuclear effects, such as final state interactions or meson rescattering. We will present preliminary results of a high statistics measurement of single and double pion photoproduction of quasi-free protons and neutrons off the deuteron carried out at the Mainzer Microtron.
