Abstract

The branching ratios of the decay of the tau lepton to five charged hadrons have been measured with the OPAL detector at LEP using data collected between 1991 and 1995 at e(+)e(-) centre-of-mass energies close to the Z(0) resonance. The branching ratios are measured to be B(tau(-) --> 3h(-)2h(+)v(tau)) = (0.091 +/- 0.014 +/- 0.006)% B(tau(-) --> 3h(-)2h(+)pi(0)v(tau)) = (0.027 +/0 0.018 +/- 0.009)% where the first error is statistical and the second systematic.
