Abstract
The Standard Model prediction of the lifetime is discussed, together with the dominant uncertainties and strategies on how to improve them. Furthermore, a new method to compute the lifetime based on the operator product expansion is proposed. It relies on differences of and meson decay rates, in which the free-quark contributions cancel out, reducing the uncertainty of the theory prediction.
