| Abstract: | A tight bound is derived on the F → φπ decay rate from current algebras and a few safe assumptions which are well justified theoretically and experimentally. In terms of the branching ratio and the F meson lifetime, the bound is written as B(F → φπ) ? (2.1 × 1011) s?1 × τF. No soft-pion limit is taken to derive the bound. |
