Abstract
The Standard Model decay rate of the meson is discussed together with a novel approach based on the usage of experimental data in combination with an operator product expansion. In the new method differences of and meson decay rates are considered, for which the free-quark contributions drop out, leading to a reduction of the theory prediction.
