| contents | 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. |
