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, the relatively small width \(\varGamma _{d^*}\approx 70\) MeV favors hadronic structure for the d\(^*\)(2380) dibaryon rather than a six-quark structure.

Acknowledgements

I’m indebted to the organizers of the Frontiers of Science symposium in memory of Walter Greiner, held at FIAS, Frankfurt, June 2017, particularly to Horst Stöcker, for inviting me to participate in this special event and for supporting my trip. Special thanks are due to Humberto Garcilazo, together with whom the concept of pion assisted dibaryons was conceived, and also due to Heinz Clement for many stimulating exchanges on the physics of dibaryons and Jerry Miller for instructive discussions on 6q contributions to dibaryons.
