A phenomenological analysis on isospin-violating decay of X(3872) [PDF]
, 2021 In a molecular scenario, we investigate the isospin-breaking hidden charm decay processes of X (3872), i.e., $$X(3872) \rightarrow \pi ^+ \pi ^- J/\psi $$ X ( 3872 ) → π + π - J / ψ , $$X(3872) \rightarrow \pi ^+ \pi ^- \pi ^0 J/\psi $$ X ( 3872 ) → π ...

Quarkyonic stars with isospin-flavor asymmetry [PDF]
Physical Review C, 2021 We suggest an extension to isospin asymmetric matter of the quarkyonic model from McLerran and Reddy [1]. This extension allows us to construct the β-equilibrium between quarks, nucleons and leptons.

Physics Letters B, 2023 Inspired by the recent precise data, we perform model-independently an isospin decomposition of the timelike octet baryons electromagnetic form factors.

The Dirac spectrum and the BEC-BCS crossover in QCD at nonzero isospin asymmetry
Particles, 2020 For large isospin asymmetries, perturbation theory predicts the quantum chromodynamic (QCD) ground state to be a superfluid phase of u and d ¯ Cooper pairs.

Generalizing the relativistic quantization condition to include all three-pion isospin channels [PDF]
Journal of High Energy Physics, 2020 We present a generalization of the relativistic, finite-volume, three-particle quantization condition for non-identical pions in isosymmetric QCD. The resulting formalism allows one to use discrete finite-volume energies, determined using lattice QCD, to

Effect of isospin averaging for $ppK^-$ kaonic cluster
SciPost Physics Proceedings, 2020 The kaonic cluster $ppK^-$ is described by isospin-dependent $N{\bar K}$ potentials with significant difference between singlet and triplet components. The quasi-bound state energy of the system is calculated based on the configuration space Faddeev

Generation of isospin sum rules in heavy hadron weak decays
Journal of High Energy Physics, 2023 Isospin symmetry is the most precise flavor symmetry. In this work, we propose an approach to generate isospin sum rules for heavy hadron decays without the Wigner-Eckhart invariants. The effective Hamiltonian of heavy quark weak decay is fully invariant

Determination of the stiffness of the nuclear symmetry energy from isospin diffusion [PDF]
, 2004 With an isospin- and momentum-dependent transport model, we find that the degree of isospin diffusion in heavy ion collisions at intermediate energies is affected by both the stiffness of the nuclear symmetry energy and the momentum dependence of the ...

Electromagnetic and strong isospin breaking in light meson masses
Physics Letters B, 2022 We study electromagnetic as well as strong isospin breaking effects in the isospin mass splittings of light pseudoscalar and vector mesons. To this end we employ a coupled system of quark Dyson-Schwinger and meson Bethe-Salpeter equations whose ...
