K$_{varrho}\-{3}$ form factors from current algebra
Including some straightforward consequences of analyticity and unitarity in the hard-meson current algebra approach, predictions are made for K/sub t3/ decays with a minimal set of assumptions. Consequences of a possible disagreement between theory and experiment are discussed. Making additional ass...

| description | Including some straightforward consequences of analyticity and unitarity in the hard-meson current algebra approach, predictions are made for K/sub t3/ decays with a minimal set of assumptions. Consequences of a possible disagreement between theory and experiment are discussed. Making additional assumptions about the convergence properties of certain spectral functions, the author derives the relation F/sub pi //sup 2/=F/sub K//sup 2/ without PCAC, pole dominance of spectral functions or a specific type of SU/sub 3/*SU/sub 3/ symmetry breaking. (19 refs). |
