Hadronic matrix elements for TAUOLA: 3 pi and KK pi channels

AuthorsRoig, Pablo
Issue DateApr-2009
CitationNuclear Physics - Section B-PS - Proceedings Supplements 1869: 78-83 (2009)
AbstractWe emphasize that the motivation for including our hadronic matrix elements in TAUOLA is not only theoretical. We also show that our expressions describe better the tau to 3pi ALEPH data and are able to fit BABAR data on the isovector component of e^+e^- -> KKpi. The theoretical foundations of our framework are the large-N_C limit of QCD, the chiral structure exhibited at low energies and the proper asymptotic behaviour, ruled by QCD, that is demanded to the associated form factors.
