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

The experimental data on the processes [pi][pi] arrow right [pi][pi], KK, [eta][eta], [eta][eta]' in the I super(G) J super(PC) = 0 super(+)0 super(++) channel have been jointly analyzed to study the status and nature of the [functionof] sub(0). The method of analysis is based on analyticity an...

Description
Summary:The experimental data on the processes [pi][pi] arrow right [pi][pi], KK, [eta][eta], [eta][eta]' in the I super(G) J super(PC) = 0 super(+)0 super(++) channel have been jointly analyzed to study the status and nature of the [functionof] sub(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.
