A measurement of the branching fraction of the decays of the tau- lepton to 2pi- pi+ eta nu
We investigate the decay mode τ − → π − π + π − ηντ , where the η subsequently decays to π + π − π 0 using 232 fb−1 data acquired by the BABAR detector. The branching fraction of τ − → π − π + π − ηντ is found to be (1.88 ± 0.14 ± 0.11) × 10−4 . The first error on the is measurement is purely sta...
