An alternative explanation of the dibaryon suggested by experiments at the WASA facility at the FZ Julich Cooler synchrotron

TL;DR

This paper critiques the claimed dibaryon resonance at 2370 MeV from WASA experiments, proposing an alternative explanation based on a different reaction mechanism supported by recent experimental evidence.

Contribution

It introduces a new interpretation of the experimental data, challenging the previous dibaryon resonance claim and suggesting an alternative reaction process.

Findings

Logical flaws in the previous dibaryon resonance claim.

Support for the alternative reaction mechanism from recent experiments.

Proposes a different explanation for the observed phenomena.

Abstract

A series of publications of the WASA collaboration culminates in a recent paper of Pricking, Bashkanov and Clement [1] claiming a dibaryon resonance at 2370 MeV. However, as explained here, there are logical flaws in this result. A natural alternative arises from the reaction pd -> N N*(1440)p_s where p_s is a spectator proton. There is supporting evidence from a recent experiment of Mielke et al. on dp -> 3He-piplus-piminus
