QCD determination of theA 1-ρ-π system through vertex light-cone sum rules

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

We analyze the ρ-A 1-π system within the context of vertex light-cone sum rules, which are believed to be rigorously satisfied in QCD. It is pointed out that these sum rules provide very strong constraints on the hadronic spectrum and with additional assumptions lead to new predictions, which go significantly beyond those obtained from current algebra in the past. In particular, we report some new results about the ρ-A 1-π couplings and the various transition form factors in τ-semi-leptonic decays.
