英文摘要 | Exclusive semileptonic B decays into excited charmed mesons (D-1, D-2*) are studied up to the order of 1/m(Q) in the framework of the heavy quark effective field theory (HQEFT), which contains the contributions of both particles and antiparticles. Two wave functions eta (b)(0) and eta (c)(0), which characterize the contributions from the kinematic operator at the order of 1/m(Q), are calculated by using QCD sum rule approach in HQEFT. Zero recoil values of other two wave functions kappa (1)' and kappa (2)' are extracted from the excited charmed-meson masses. Possible effects from the transition wave functions arising from the chromomagnetic operators at the order of 1/m(Q) are analyzed. It is shown that the experimental measurements for the branching ratios of B --> D(1)lv and B --> D-2*lv can be understood in the framework of HQEFT. |
