On nature of the scalar-isoscalar mesons in the uniformizing-variable method based on analyticity and unitarity

Abstract

The experimental data on the processes $ππ\toππ,K\bar{K},ηη,ηη^\prime$ in the $I^GJ^{PC}=0^+0^{++}$ channel have been jointly analyzed to study the status and nature of the $f_0$. The method of analysis is based on analyticity and unitarity and uses an uniformization procedure. Some spectroscopic implications from results of the analysis are discussed.
