Abstract
We use the Linear Sigma Model to test the convergence of different sequences of Padé Approximants when used to unitarize the low energy ππ scattering amplitude. We find that, in this particular case, diagonal sequences reproduce the sigma pole with high accuracy, as opposed to other sequences that have been discussed extensively.
