CKM Matrix: Status and New Developments

Abstract

An analysis of the CKM matrix parameters within the {\it R}fit approach is presented using updated input values with special emphasis on the recent $\sin 2\beta$ measurements from BABAR and Belle. The QCD Factorisation Approach describing $B\to \pi \pi ,K\pi$ decays has been implemented in the software package CKMfitter. Fits using branching ratios and CP asymmetries are discussed.
