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 ...

Lifetimes of singly charmed hadrons

Journal of High Energy Physics, 2022
We provide an extensive study of the lifetimes of singly charmed baryons and mesons, within the heavy quark expansion with all known corrections included.

Hadrons in Nuclei: Experiments and Perspectives [PDF]

, 2007
The question of the origin of hadron masses is one major issue in the understanding of the strong interaction. The challenge is addressed by searching for indications of in-medium modifications of hadron properties and studying hadrons in nuclei.

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.

Diquarks: properties and their role in hadrons [PDF]

AIP Conference Proceedings, 2005
Diquark correlations are important in baryons, which can be modeled as quark-diquark bound states. In addition, diquarks could play a role in non-standard hadrons such as tetraquarks and pentaquarks. Here, we obtain properties of these diquarks from the corresponding bound state equation, using a model for the effective quark-quark interaction that has

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 +

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.
