The decay τ-→K-K+π-ντ and the ντ mass

9 páginas, 4 figuras, 2 tablas.In this paper, we present a model based on the effective chiral Lagrangian to describe the decay τ-→K-K+π-ντ. Using our model we study the possible limits on the ντ mass that can be achieved by a high-statistics, high-precision experiment taking data close to the τ-pair production threshold.The work of two of us (M.C.G-G. and A.P.) has been partially supported by CICYT, Spain, under Grant No. AEN 89-0348.
