Refining the scalar and tensor contributions in τ → πππν τ decays

Refining the scalar and tensor contributions in τ → πππν τ decays

Abstract In this article we analyze the contribution from intermediate spin-0 and spin-2 resonances to the τ → νπππ decay by means of a chiral invariant Lagrangian incorporating these mesons. In particular, we study the corresponding axial-vector form-factors. The advantage of this procedure with re...
