# Strange and charmed baryon productions with an instanton interaction

## TL;DR

This paper investigates strange and charmed baryon production mechanisms, introducing a novel two-quark process based on instanton-induced interactions, which allows excitation of different baryon modes and relates production rates to baryon structure.

## Contribution

It proposes a new two-quark production mechanism involving instanton effects, enabling excitation of multiple baryon modes and linking production rates to baryon internal structure.

## Key findings

- Two-quark process enhances baryon excitation possibilities.
- Instanton interactions significantly influence production rates.
- Forward scattering analysis reveals structure-dependent production patterns.

## Abstract

We study strange and charmed baryon productions, ${\pi + p \rightarrow K(D) + Y(Y_c)}$, where ${Y(Y_c)}$ is a strange(charmed) baryon of a ground or an excited state. We propose a new production mechanism where two quarks in the baryon participate in the reaction (two-quark process), which enables excitation of both ${\lambda}$- and ${\rho}$-modes of the baryons. To deal with the two-quark process, we consider the 't Hooft six-quark interaction from the instanton model. We study production rates in relation with the structure of charmed baryons for the forward angle scattering.
