Abstract

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