The В → D(D*)ev-decay amplitude factorization and the Isgur-Wise function calculation
Λ new approach to the relativistic system of heavy and light quarks is formulated in which a light quark is supposed to be confined whereas a heavy quark behaves as usual Fermi particle with large mass. The form factors for the В —» D(D*)ev-decay are calculated within this approach. The Isgur-Wise function is obtained in the heavy quark limit Mq —♦ со.
