Dispersive analysis of τ− → π−π⁰ντ Belle data

We analyse Belle data on the decay τ− → π−π⁰ν<sub>τ</sub> using a dispersive representation of the vector form factor which is consistent with chiral symmetry and preserves analyticity and unitarity exactly. We fit the unknown theoretical parameters from the data, determining the values...
