Pion assisted dibaryons: the d*(2380) resonance

Abstract

The structure and width of the recently established d*(2380) resonance are discussed, confronting the consequences of a Pion Assisted Dibaryons hadronic model with those of quark motivated calculations. In particular, the small width Γd*≈70$\Gamma_{d\ast}\approx70$ MeV favors hadronic structure for the d*(2380) dibaryon rather than a six-quark structure.
