Charmed baryon Sigmac(2800) as a ND hadronic molecule

TL;DR

This paper investigates the Sigmac(2800) baryon as a hadronic molecule formed by a nucleon and a D meson, analyzing decay widths to match experimental data for certain quantum number assignments.

Contribution

It proposes a molecular interpretation of Sigmac(2800) and calculates decay widths consistent with observed data for specific quantum states.

Findings

Decay widths match experimental data for J(P)=1/2(+)

Decay widths match experimental data for J(P)=3/2(-)

Supports molecular structure hypothesis for Sigmac(2800)

Abstract

The isotriplet Sigmac(2800) baryon with possible quantum numbers J(P) = 1/2(+), 1/2(-) or 3/2(+), 3/2(-) is considered as a hadronic molecule composed of a nucleon and a D meson. We determine the strong two-body decay widths Sigmac to Lambdac + pi which are shown to be consistent with current data for the J(P) = 1/2(+) and J(P) = 3/2(-) assignments.
