The nonleptonic decays of b-flavored mesons to S-wave charmonium and charm meson states

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
The detection of radially excited charmonium and charm meson states, and measurement of heavy meson decays, particularly $$B_c^+\rightarrow J/\psi D_s^+$$ B c + → J / ψ D s + and $$B_c^+\rightarrow J/\psi D_s^{*+}$$ B c + → J / ψ D s ∗ + , by the LHCb ...

A connection between inclusive semileptonic decays of bound and free heavy quarks [PDF]

open access: yes, 1997
A relativistic constituent quark model, formulated on the light-front, is used to derive a new parton approximation for the inclusive semileptonic decay width of the B-meson. A simple connection between the decay rate of a free heavy-quark and the one of

Re-examining sin⁡2β and Δmd from evolution of Bd0 mesons with decoherence

open access: yesPhysics Letters B, 2015
In the time evolution of neutral meson systems, a perfect quantum coherence is usually assumed. The important quantities of the Bd0 system, such as sin⁡2β and Δmd, are determined under this assumption.

B-MESON DISTRIBUTION AMPLITUDES [PDF]

open access: yesInternational Journal of Modern Physics A, 2005
B-meson light-cone distribution amplitudes are discussed in these lectures in the framework of HQET. The evolution equation for the leading-twist distribution amplitude is derived in one-loop approximation. QCD sum rules for distribution amplitudes are discussed.

RADIATIVE B MESON DECAY [PDF]

open access: yesB Physics and CP Violation, 2001
We studied radiative B meson decays with the Belle detector. We measured the following branching fractions; Br(B->K*0(892) ) = (49.6 \pm 6.7 \pm 4.5) x 10^{-6}, Br(B->K*+(892) ) = (38.9 \pm 9.3 \pm 4.1) x 10^{-6}, Br(B->Xs ) = (3.39 \pm 0.53 \pm 0.42 +0.51-0.55) x 10^{-4}.

Study of B Meson Decays with Excited eta and eta' Mesons [PDF]

open access: yesPhysical review letters, 2008
Using 383 million BBbar pairs from the BaBar data sample, we report results for branching fractions of six charged B-meson decay modes, where a charged kaon recoils against a charmless resonance decaying to KKbar* or etapipi final states with mass in the range (1.2-1.8)gev/c^2. We observe a significant enhancement at the low KK*bar invariant mass which

The decays of $$\bar{B}^0$$ B¯0 , $$\bar{B}^0_s$$ B¯s0 and $$B^-$$ B- into $$\eta _c$$ ηc plus a scalar or vector meson

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We investigate the decays of $$\bar{B}^0_s$$ B¯s0 , $$\bar{B}^0$$ B¯0 and $$B^-$$ B- into $$\eta _c$$ ηc plus a scalar or vector meson in a theoretical framework by taking into account the dominant process for the weak decay of $$\bar{B}$$ B¯ meson into $

B to light meson transition form factors calculated in perturbative QCD approach [PDF]

open access: yes, 2002
We calculate the $B\to P$, $B\to V$ (P: light pseudoscalar meson, V light vector meson) form factors in the large-recoil limit in perturbative QCD approach, including both the vector (axial vector) and tensor operators.
