Pion- and photo-induced transition amplitudes to $\Lambda K$, $\Sigma K$, and $N\eta$

TL;DR

This paper analyzes pion- and photo-induced reactions on protons using multichannel partial-wave analysis to extract properties of nucleon and delta resonances and their transition amplitudes to various final states.

Contribution

It introduces a comprehensive multichannel partial-wave analysis to study transition amplitudes to multiple final states, updating resonance properties with new data.

Findings

Resonance properties are derived and compared to previous analyses.

Transition amplitudes to $N\,\eta$, $\Lambda K$, and $\Sigma K$ are presented.

The analysis enhances understanding of nucleon and delta resonance structures.

Abstract

Pion and photo-induced inelastic reactions off protons are studied in a multichannel partial-wave analysis. Properties of nucleon and $\Delta$ resonances are derived and compared to previous analyses. Amplitudes are shown for transitions to $N\eta$, $\Lambda K$, and $\Sigma K$ final states.
