Low energy pion double charge exchange reactions and dibaryon

الملخص EN

A common characteristic of low energy pion-nucleus double charge exchange reactions is a resonance like peak around 50 MeV.

It has been claimed [1] that this peak provides evidence for the existence of hypothetical Dibaryon resonance d (2.06 GeV) at this energy.

This article will show how this peak could be predicted using conventional sequential mechanism without invoking Dibaryon degrees of freedom PACS numbers: 25.80.Gn, 24.30.Gd.
