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 statistical and the second error is estimated systematic
error. This measurement is consistent with the prior experimental mesaurements at
CLEO and BABAR.
