Phys. Rev. D 60, 076006 (1999) [6 pages]Constraining the CKM parameters using CP violation in semileptonic B decaysReceived 10 May 1999; published 13 September 1999 We discuss the usefulness of the CP violating semileptonic asymmetry aSL not only as a signal of new physics, but also as a tool in constraining the Cabibbo-Kobayashi-Maskawa parameters. We show that this technique could yield useful results in the first years of running at the B factories. We present the analysis graphically in terms of M12, the dispersive part of the B0-B0 mixing amplitude. This is complementary to the usual unitarity triangle representation and often allows a cleaner interpretation of the data. © 1999 The American Physical Society URL:
