Hadronic structure in the decay τ-→ντπ-π 0π0 and the sign of the tau neutrino helicity

Hadronic structure in the decay τ-→ντπ-π 0π0 and the sign of the tau neutrino helicity

Based on a sample corresponding to 4.3×106 produced τ-pair events, we have studied hadronic dynamics in the decay τ-→ντπ-π 0π0 in data recorded by the CLEO II detector operating at the CESR e+e- collider. The decay is dominated by the process τ-→ντa1-(1260), with the a1- meson decaying to three pion...
