We investigate the semileptonic decay of $\Omega_b\to\Omega_c~{\ell}\bar\nu_ {\ell} $ in
three lepton channels. To this end, we use QCD sum rule method in three point framework to …

The tree-level b→ c ℓ ν¯ ℓ based hadronic transitions have been the focus of much attention
since recording significant deviations of the experimental data, on the ratios of the branching …

We calculate the transition form factors of the semileptonic B_c→c2lν in the framework of
QCD sum rules taking into account the two-gluon condensate corrections. Using the …

We investigate the structure of the D_ 1^ 0 (2420 2430)(J^ P= 1^+) D 1 0 (2420 2430)(JP=
1+) mesons via analyzing the semileptonic B_ c → D_ 1^ 0 l ν B c→ D 1 0 l ν transition in the …

The semileptonic decay of the b is particularly elegant from the standpoint of experimental
and theoretical investigations. The b is the most copiously produced bottom quark baryon; in …

Taking into account the Λ baryon distribution amplitudes and the most general form of the
interpolating current of the Λ b, the semileptonic Λ b→ Λ ℓ+ ℓ-transition is investigated in the …

In the framework of the factorization approach we calculate the branching fractions of 100
two-body nonleptonic decay channels in total, including 44 channels of the charm meson …

A comprehensive study of b→ c weak decays of doubly heavy baryons is presented in this
paper. The transition form factors as well as the pole residues of the initial and final states …

Very recently, the LHCb collaboration has observed in the final state Λ _c^+ K^-π^+ π^+ Λ
c+ K-π+ π+ a resonant structure that is identified as the doubly charmed baryon Ξ _ cc^++ Ξ …

The investigation of long-lived heavy quarkonium Bc composed of quarks with different
flavors can produce a significant progress in the study of heavy quark dynamics, since the …
