Abstract
- Making full use of a high-statistical data sample of τ decays recorded in the KEKB-Belle experiment, we have largely improved the precision of the branching fraction , and measured the mass and width of meson to be and , respectively, with better or similar accuracy of the PDG world average values. The first measurement of decay is also accomplished and is obtained. (All results presented here are preliminary.) [Copyright &y& Elsevier]
