“…The pole fit reproduces both the drop in A y , seen in the lower energy data of Ref. [18], and the rapid rise displayed in the COSY data. Also shown is a revised fit without a pole, which takes an averaging path through the data without any rapid variation.…”

Sensitivity of the COSY dibaryon candidate tonpelastic scattering measurements

2016

View full text Add to dashboard Cite

The case for a dibaryon resonance, appearing in np scattering, has support from a WASA-at-COSY measurement of the polarization quantity Ay over a center-of-mass energy region suggested by structures seen earlier in two-pion production experiments. Here we compare fits with and without an associated pole in order to clarify the impact of these COSY data. We then consider what further np scattering measurements would most clearly distinguish between the pole and nonpole fit results.
