Abstract
We analyze the tauonic semileptonic baryon decays with particular emphasis on the lepton helicity flip contributions which vanish for zero lepton masses. We calculate the total rate, differential decay distributions, the longitudinal and transverse polarization components of the and the , and the lepton-side forward-backward asymmetries. We use the covariant confined quark model to provide numerical results on these observables.
