The Effective Chiral Lagrangian with Vector Mesons and Hadronic τ Decays

摘要

We study the chiral Lagrangian including the vector mesons such as K~* and p. The one loop corrections to vector form factors including the chiral breaking is studied. Once we obtain the form factors, one can study the hadronic tau decay τ→ Kπυ and compute the hadronic invariant distribution.
