Abstract
We have analyzed one-prong Τ decays with neutral kaons using the information from a fine-grained hadron calorimeter. The data sample consists of 43 500 Z → Τ+Τ−(γ) events collected by the L3 detector at LEP in 1991, 1992 and 1993. The following branching fractions are measured: B(Τ−→νΤπ−K̅ 0) = 0.0095±0.0015(stat)±0.0006(syst), B(Τ−→νΤπ− π0K̅0) = 0.0041±0.0012(stat)±0.0003(syst), B(Τ−→νΤπ−K0K̅0) = 0.0031±0.0012(stat)±0.0004(syst).
