Structure and Width of the d*(2380) Dibaryon

TL;DR

This paper investigates the structure and decay width of the d*(2380) dibaryon, comparing hadronic and quark models, and finds evidence favoring a hadronic structure due to its narrow width.

Contribution

It provides a detailed analysis of the d*(2380) dibaryon, highlighting the implications of its small width for its underlying structure and contrasting different theoretical models.

Findings

The d*(2380) has a width of about 70 MeV.

Hadronic models better explain the narrow width than quark models.

Supports a hadronic structure over a six-quark configuration.

Abstract

In this contribution, dedicated to the memory of Walter Greiner, we discuss the structure and width of the recently established d*(2380) dibaryon, confronting the consequences of our Pion Assisted Dibaryons hadronic model with those of quark motivated calculations. In particular, its relatively small width of about 70 MeV favors hadronic structure for the d*(2380) dibaryon rather than a six-quark structure.
