# A three-body calculation of incoherent $\pi^0$ photoproduction on a deuteron

## TL;DR

This paper models incoherent π⁰ photoproduction on deuterons using a three-body scattering approach, finding higher order corrections negligible and unable to resolve discrepancies with experimental data.

## Contribution

It introduces a three-body scattering calculation with separable interactions for incoherent π⁰ photoproduction on deuterons, assessing higher order effects.

## Key findings

- Higher order terms are insignificant in the scattering series.
- Theoretical results do not resolve the discrepancy with experimental data.
- Total and differential cross sections are computed.

## Abstract

Incoherent $\pi^0$ photoproduction on a deuteron in the $\Delta(1232)$ region is treated in a three-body scattering approach using separable two-body interactions. Results are presented for total and differential cross sections. It turns out that the role of higher order terms beyond the first order in the multiple scattering series is insignificant, and their inclusion cannot explain the existing discrepancy between theory and experiment.
