Abstract

Using data collected in the DELPHI detector at LEP-1, measurements of the inclusive T branching ratios for decay modes containing one, three, or five charged particles have been performed, giving the following results: B-1 equivalent to B T- (particle)(-) greater than or equal to0 pi (0) greater than or equal to 0K(0) v(T) (v(overbar)) = 85.316 +/- 0.093 +/- 0.049) %; B-3 equivalent to B(T- --> 2h(-)h(+) greater than or equal to 0 pi (0) greater than or equal to0 pi (0) greater than or equal to 0K(0)z17) = (14.569 +/- 0.093 +/- 0.048)%; B-5 equivalent to B(T- --> 3h(-)2h(+) greater than or equal to 0 pi (0) greater than or equal to 0K0(0)v(T)) = (0.115 +/- 0.013 +/- 0.006)%, where h is either a charged pi or K meson. The first quoted uncertainties are statistical and the second systematic.
