The {tau}{sup -} {yields} {pi}{sup -}{pi}{sup -}{pi}{sup +}{pi}{sup 0}{pi}{sup 0}{nu}{sub {tau}} and {tau}{sup -} {yields} 3h{sup -} 2h{sup +} {nu}{sub {tau}} decays have been studied using the BABAR experiment at the PEP-II e{sup +}e{sup -} storage ring. Preliminary branching fractions are given for the {tau}{sup -} {yields} {pi}{sup -}{pi}{sup -}{pi}{sup +}{pi}{sup 0}{pi}{sup 0}{nu}{sub {tau}} and to the sub-channels {tau}{sup -} {yields} {eta}{pi}{sup -} {pi}{sup 0}{nu}{sub {tau}} and {tau}{sup -} {yields} {omega}(782){pi}{sup -}{pi}{sup 0}{nu}{sub {tau}}. A preliminary upper limit is given on the branching fraction for the {phi}(1020){pi}{sup -}{pi}{sup 0}{nu}{sub {tau}} mode. In addition a preliminary measurement of the branching fraction of the {tau}{sup -} {yields} 3h{sup -}2h{sup +} {nu}{sub {tau}} decay (h = {pi}, K) is presented.

A preliminary measurement of the branching fraction of the [tau][sup -] --> 3h[sup -]2h[sup +][nu][sub [tau]] decay (h = [pi], K) with the BABAR detector is found to be (8.52 [+-] 0.09 [+-] 0.40) x 10[sup -4], where the first error is statistical and the second is systematic. The data show evidence that the [rho] resonance plays a strong role in the decay of the [tau] lepton to five charged hadrons.

Abstract Not Provided.

A search for the decay of the {tau} lepton to seven charged pions and at most one {pi}{sup 0} was performed using the BABAR detector at the PEP-II e{sup +}e{sup -} collider. The analysis uses data recorded on and near the {Upsilon}(4S) resonance between 1999 and 2003, a total of 124.3 fb{sup -1}. They observe 7 events with an expected background of 11.9 {+-} 2.2 events and calculate a preliminary upper limit of BR({tau}{sup -} {yields} 4{pi}{sup -} 3{pi}{sup +}({pi}{sup 0}){nu}{sub {tau}})

The branching fraction of the?− → 3h− 2h?{sub?} decay (h =?, K) is measured with the BABAR detector to be (8.56 ± 0.05 ± 0.42) x 10−4, where the first error is statistical and the second systematic. The observed structure of this decay is significantly different from the phase space prediction, with the? resonance playing a strong role. The decay {tau}− → f1(1285)?−?{sub {tau}}, with the f1(1285) meson decaying to four charged pions, is observed and the branching fraction is measured to be (3.9 ± 0.7 ± 0.5) x 10−4.
