sigma and kappa

Collection of data
on the most reluctant light scalar mesons
(for references, just click on a data point and then on the corresponding year in the upper line of the table)

Below, find tabulated the real and imaginary parts of the poles for each of the datapoints.
When you click on the year then you obtain the complete reference.
When you click on return then you return to the figures.
