We have searched for the radiative leptonic tau decays[tau][yields] ee[sup+]e[sup -][nu][sub[tau]][nu][sub e] and[tau][yields][mu]e[sup+]e[sup -][nu][sub[tau]][nu][sub[mu]] using 3.60 fb[sup -1] of data collected by the CLEO-II experiment at CESR. We present a first observation of the[tau][yields] ee[sup+]e[sup -][nu][sub[tau]][nu][sub e] process. For this channel we measure the branching fraction B([tau][yields] ee[sup+]e[sup -][nu][sub[tau]][nu][sub e])= (2.8[+-] 1.4[+-] 0.4) x 10[sup -5]. An upper limit is established for the second channel: B([tau][yields][mu]e[sup+][nu][sub[tau]][nu][sub[mu]])

We present {tau}{sup -} lepton branching fraction measurements based on data from the TPC/Two-Gamma detector at PEP. Using a sample of {tau}{sup -} {yields} {nu}{sub {tau}}K{sup -}{pi}{sup +}{pi}{sup -} events, we examine the resonance structure of the K{sup -}{pi}{sup +}{pi}{sup -} system and obtain the first measurements of branching fractions for {tau}{sup -} {yields} {nu}{sub {tau}}K{sub 1}{sup -}(1270) and {tau}{sup -} {yields} {nu}{sub {tau}}K{sub 1}{sup -}(1400). We also describe a complete set of branching fraction measurements in which all the decays of the {tau}{sup -} lepton are separated into classes defined by the identities of the charged particles and an estimate of the number of neutrals. This is the first such global measurement with decay classes defined by the four possible charged particle species, e, {mu}, {pi}, and K.

Semileptonic B meson decays into final states containing the [tau] lepton are of interesting as they provide information on the Standard Model as well as a window on new physics effects. We present results on {bar B} → D{sup (*)} [tau]{bar {nu}}{sub {tau}} decays where the second B in the event is fully reconstructed.
