D.V. Bugg (Queen Mary, University of London)
TL;DR
This paper predicts a new pole in the D-pi S-wave at around 2098 MeV with a broad width, and provides formulas for experimental data fitting.
Contribution
It introduces a theoretical prediction of a D-pi S-wave pole and offers practical formulas for data analysis.
Findings
Predicted a D-pi S-wave pole at 2098 MeV
Estimated the pole's width as approximately 520 MeV
Provided fitting formulas for experimental data
Abstract
A pole in the D-pi S-wave analogous to the sigma and kappa is predicted at 2098 +- 40 - i(260 +- 40) MeV. The main objective of this paper is to provide formulae for fitting it to data.
