====== TTP02-38 Two-Loop Electroweak Corrections to $\Delta r$ ====== The two-loop electroweak bosonic correction to the muon lifetime is computed using methods of asymptotic expansion. Combined with previous calculations this completes the full two-loop correction to $\Delta r$ in the Standard Model. |**A. Onishchenko, O. Veretin** | |** Nucl.Phys.
