Abstract
We discuss recent higher order calculations to properties of mesons. This includes next-to-next-to-leading order corrections to nonleptonic and next-to-next-to-next-to-leading order corrections to semileptonic meson decays. The latter is important in connection to the determination of the CKM matrix element . We also discuss next-to-next-to-leading order corrections to the width difference in the neutral meson system.
