QCD light-cone distribution amplitudes of heavy mesons from boosted HQET

Journal of High Energy Physics, 2023
Light-cone distribution amplitudes (LCDAs) frequently arise in factorization theorems involving light and heavy mesons. The QCD LCDA for heavy mesons includes short-distance physics at energy scales of the heavy-quark mass.

Radial excitations of heavy-light mesons from QCD sum rules [PDF]

, 2014
QCD sum rules are commonly used to predict the characteristics of ground-state hadrons. We demonstrate that two-point sum rules for the decay constants of charmed ($D^{(*)},D_s^{(*)}$) and bottom ($B^{(*)},B_s^{(*)}$) mesons can also be modified to ...

Cabibbo-suppressed non-leptonic B- and D-decays involving tensor mesons [PDF]

, 1998
The Cabibbo-suppressed non-leptonic decays of B (and D) mesons to final states involving tensor mesons are computed using the non-relativistic quark model of Isgur-Scora-Grinstein-Wise with the factorization hypothesis. We find that some of these B decay

Spectroscopy of the excited Ds mesons [PDF]

EPJ Web of Conferences, 2022
The discoveries of the Ds0*(2317)+Ds0∗(2317)+ and Ds1(2460)+ mesons challenge our understanding of quantum chromodynamics. After almost 20 years, the nature of these hadrons is still subject of debate and many models have been proposed to explain their ...

Non-factorization effects in heavy mesons and determination of |V_{ub}| from inclusive semileptonic B decays [PDF]

, 2001
The effects of spectator light quark in decays of heavy mesons are considered, which vanish in the limit of factorization of matrix elements of four-quark operators over the mesons.

Production of D0 meson in pp and PbPb Collisions at √SNN = 5.02 TeV with CMS

EPJ Web of Conferences, 2018
Heavy flavour mesons are used as powerful tools for the study of the strongly interacting medium in heavy ion collisions as heavy quarks are sensitive to the transport properties of the medium.

Purely leptonic decays of the ground charged vector mesons

European Physical Journal C: Particles and Fields, 2021
The study of the purely leptonic decays of the ground charged vector mesons is very interesting and significant in determining the CKM matrix elements, obtaining the decay constant of vector mesons, examining the lepton flavor universality, and searching

B decays into two light pseudoscalar mesons and possible effects of enhanced b --> s g

, 1998
We consider the branching ratios and CP asymmetry in the B meson decays into two pseudoscalar mesons in the generalized factorization approximation. We also investigate the possible effects of the enhanced chromomagnetic interaction b --> s g on these ...

Reconstruction of B mesons

Physics Letters B, 1987
Abstract B mesons have been reconstructed in five decay channels of the type B →D ∗ ±nπ(n=1,2,3) using data accumulated by the ARGUS experiment at the e + e − storage ring DORIS II at DESY. In total, we find 40 neutral B mesons above a background of 15±6 events with a mass of (5278.2±1.0±3.0) MeV/ c 2 and 32 charged B mesons above a ...
