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 ...

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.

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.

Property of recombination in polarized hadronic targets [PDF]

Physical Review D, 1994
The triple gluon-ladder vertex is shown to project the outgoing gluon in either polarization state with equal probability up to the leading double-ln(x)ln($Q^2$) approximation. This implies that the $Q^2$-evolution of $ G (x, Q^2)$ is free from recombination effects to this level of approximation.

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 +

Hadronic properties of the photon [PDF]

EPJ Web of Conferences, 2019
Currently it is no doubt that high energy photons (real or virtual) have a hadronic component leading to photon shadowing in its interaction with nuclei. We shortly consider the difficulties appeared in the models like vector dominance model (VDM) and stress that these problems can be solved in a color dipole model inspired by Quantum Chromodynamics ...

Gravitational transition form factors of N → ∆ via QCD light-cone sum rules

Journal of High Energy Physics, 2023
We present the first direct calculation on the gravitational form factors (GFFs) of the N → ∆ transition using an analytic method, the QCD light-cone sum rules. The matrix element of the quark part of the energy momentum tensor current sandwiched between
