Strange-quark mass effects in the B s meson’s light-cone distribution amplitude
Journal of High Energy Physics, 2023 We investigate the differences between the light-cone distribution amplitudes (LCDAs) of B s mesons and B q mesons (with q = u, d) induced by a non-vanishing strange-quark mass m s ≠ 0 (compared to m q ≃ 0).

Isospin mass differences of the B, D and K
Journal of High Energy Physics, 2023 We compute the electromagnetic mass difference for the B-, D- and K-mesons using QCD sum rules with double dispersion relations. For the B- and D-mesons we also compute the linear quark mass correction, whereas for the K the standard soft theorems prove ...

Averages of b-hadron, c-hadron, and τ-lepton properties as of 2018 [PDF]
European Physical Journal C: Particles and Fields, 2019 This paper reports world averages of measurements of $b$-hadron, $c$-hadron, and $τ$-lepton properties obtained by the Heavy Flavor Averaging Group using results available through September 2018. In rare cases, significant results obtained several months later are also used.

Hadronic Property at Finite Density [PDF]
Progress of Theoretical Physics Supplement, 2004 We report on three topics on finite density simulations: (i) the derivative method for hadronic quantities, (ii) phase fluctuations in the vicinity of the critical temperature and (iii) the density of states method at finite isospin density.

Kinked tracks from Σ + baryons as a probe of light quark polarizations
Journal of High Energy Physics, 2023 Jets initiated by energetic quarks carry in an obvious way approximate information about the original quark energy and momentum. In a less obvious way, they also carry information about the quark polarization.

Revisiting lifetimes of doubly charmed baryons
Journal of High Energy Physics, 2023 We present updated predictions for lifetimes of doubly charmed baryons, within the heavy quark expansion, including available NLO α s contributions and newly-computed terms in the 1/m c series. Our improved results confirm the expected hierarchy τ Ξ cc +
