K. Azizi,* H. Sundu, and S. Şahin Department of Physics, Doğuş University, Acıbadem-Kadıköy, 34722 Istanbul, Turkey Department of Physics, Kocaeli University, 41380 Izmit, Turkey (Received 6 May 2013; revised manuscript received 18 July 2013; published 9 August 2013) The transition form factors of the semileptonic B ! D 2ð2460Þ‘ ð‘ 1⁄4 ; ; eÞ decay channel are calculated within the framework of the three-point QCD sum rules. The fit functions of the form factors are then used to estimate the total decay width and branching ratio of this transition. The order of branching ratio shows that this channel can be detected at the LHCb.

متن کاملSemileptonic Decay of B-Meson into D and the Bjorken Sum Rule
We study the semileptonic branching fraction of B-meson into higher resonance of charmed meson D by using the Bjorken sum rule and the heavy quark effective theory(HQET). This sum rule and the current experiment of B-meson semileptonic decay into D and D predict that the branching ratio into Dlνl is about 1.7%. This predicted value is larger than the value obtained by the various theoretical ha...
متن کاملSemileptonic B Decays to Excited Charm Mesons
Exclusive semileptonic B decays to the lightest excited charmed mesons are investigated at order ΛQCD/mQ in the heavy quark effective theory. At zero recoil, ΛQCD/mQ corrections to the matrix elements of the weak currents can be written in terms of the leading Isgur-Wise functions for the corresponding transition and meson mass splittings. The differential decay rates are predicted, including Λ...
متن کاملQuantitative Predictions for B semileptonic decays into D, D∗ and the orbitally excited D∗∗ in quark models à la Bakamjian-Thomas
Once chosen the dynamics in one frame, the rest frame in this paper, the Bakamjian and Thomas method allows to define relativistic quark models in any frame. These models have been shown to provide, in the infinite quark mass limit, fully covariant current form factors as matrix elements of the quark current operator. In this paper we use the rest frame dynamics fitted from the meson spectrum b...
متن کاملSemileptonic B decays to excited charmed mesons
Exclusive semileptonic B decays into excited charmed mesons are investigated at order ΛQCD/mQ in the heavy quark effective theory. Differential decay rates for each helicity state of the four lightest excited D mesons (D1, D ∗ 2, D∗ 0, andD ∗ 1) are examined. At zero recoil, ΛQCD/mQ corrections to the matrix elements of the weak currents can be written in terms of the leading IsgurWise function...
