摘要：
In the framework of QCD sum rules we evaluate the B meson semileptonic transitions to positive-parity charmed states. We consider the limit of infinitely heavy quarks and determine the two universal Isgur-Wise functions. We also compare this description with the results obtained for finite values of heavy-quark masses. The computed branching ratios for these decays are of the order of 10(-3).
