QCD at finite isospin chemical potential [PDF]
, 2017 We investigate the properties of QCD at finite isospin chemical potential at zero and non-zero temperatures. This theory is not affected by the sign problem and can be simulated using Monte-Carlo techniques. With increasing isospin chemical potential and

Study of Semileptonic B⟶DPℓ+νℓ Decays Based on the SU(3) Flavor Symmetry
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.Decays B⟶DPℓ+νℓ(ℓ = e, μ, τ) with the nonresonance, the charmed vector resonances, the charmed scalar resonances, and the charmed tensor resonances are explored by using the SU(3) flavor symmetry approach. Firstly, the decay amplitudes of different modes are related by the SU(3) flavor symmetry.

Isospin splittings in baryons with two heavy quarks [PDF]
, 2017 Isospin splittings in baryons with two heavy quarks and a $u$ or $d$ quark are calculated using simple methods proposed previously by the authors. The results are $M(\Xi_{cc}^{++})-M(\Xi_{cc}^+) = 1.41 \pm 0.12^{+0.76}$ MeV, $M(\Xi_{bb}^0) - M(\Xi_{bb}^

, 2014 In the Skyrme model atomic nuclei are modelled as quantized soliton solutions in a nonlinear field theory of pions. The mass number is given by the conserved topological charge $B$ of the solitons. Conventionally, Skyrmions are semiclassically quantized within the rigid body approach.

Quarks unter Hochdruck im Proton
Physik in unserer Zeit, Volume 55, Issue 6, Page 298-306, November 2024.Schon vor etwa 90 Jahren haben Experimente gezeigt, dass das Proton kein punktförmiges Elementarteilchen ist, wie das Elektron, sondern eine innere Struktur aufweist. Dies war der Beginn der Protonstrukturforschung, die vor Kurzem mit der Messung des Drucks im Innern des Protons einen spannenden Höhepunkt erreicht hat.

European Physical Journal C: Particles and FieldsWe pursue the calculation of the model-independent component of the axion-photon-photon coupling in the U(3) chiral perturbation theory up to next-to-leading order, with the emphasis on the isospin breaking effect.

Probing the isospin mixing in the 72Kr compound nucleus via GDR γ decay
Physics Letters BThe isospin mixing was deduced in the compound nucleus 72Kr at a low nuclear temperature around 1.3 MeV, from the γ decay of the giant dipole resonance.

Isospin-symmetry breaking in masses of N≃Z nuclei
Physics Letters B, 2018 Effects of the isospin-symmetry breaking (ISB) beyond mean-field Coulomb terms are systematically studied in nuclear masses near the N=Z line. The Coulomb exchange contributions are calculated exactly.
