Regge-plus-resonance predictions for neutral-kaon photoproduction from the deuteron

TL;DR

This paper develops a Regge-inspired effective-Lagrangian model to predict neutral-kaon photoproduction from the deuteron, extending previous charged-kaon models and comparing favorably with experimental data.

Contribution

It introduces a novel transformation of the Regge-plus-resonance model to describe neutral-kaon production from neutrons and protons within the deuteron.

Findings

Model accurately reproduces existing 2H(gamma,K0)YN data.

Extends charged-kaon production models to neutral-kaon case.

Provides a framework for future experimental comparisons.

Abstract

We present a Regge-inspired effective-Lagrangian framework for neutral-kaon photoproduction from the deuteron. Quasi-free kaon production is investigated using the Regge-plus-resonance elementary operator within the relativistic plane-wave impulse approximation. The Regge-plus-resonance model was developed to describe photoinduced and electroinduced charged-kaon production off protons. We show how this elementary operator can be transformed to account for the production of neutral kaons from both protons and neutrons. Our results compare favourably to the sole 2H(gamma,K0)YN dataset published to date.
