Two- and Three-Pion Finite-Volume Spectra at Maximal Isospin from Lattice QCD. [PDF]
Physical Review Letters, 2019 We present the three-pion spectrum with maximal isospin in a finite volume determined from lattice QCD, including excited states in addition to the ground states across various irreducible representations at zero and nonzero total momentum.

Isospin-violating dark matter [PDF]
Physics Letters B, 2011 Searches for dark matter scattering off nuclei are typically compared assuming that the dark matter's spin-independent couplings are identical for protons and neutrons. This assumption is neither innocuous nor well motivated. We consider isospin-violating dark matter (IVDM) with one extra parameter, the ratio of neutron to proton couplings, and include

, 2003 We study the isospin effects of the mean field and two-body collision on the nucleon emissions at the intermediate energy heavy ion collisions by using an isospin dependent transport theory.

Probing the symmetry energy and the degree of isospin equilibrium [PDF]
, 2006 The rapidity dependence of the single- and double- neutron to proton ratios of nucleon emission from isospin-asymmetric but mass-symmetric reactions Zr+Ru and Ru+Zr at energy range $100 \sim 800$ A MeV and impact parameter range $0\sim 8$ fm is ...

Exclusive measurement of isospin mixing at high temperature in 32S
Physics Letters B, 2016 Exclusive measurement of isospin (I) mixing in 32S at high temperature (T) has been performed utilizing the γ-decay of isovector giant dipole resonance (IVGDR).

Isospin Diffusion in Heavy-Ion Collisions and the Neutron Skin Thickness of Lead
, 2005 The correlation between the thickness of the neutron skin in Pb-208, and the degree of isospin diffusion in heavy-ion collisions is examined. The same equation of state is used to compute the degree of isospin diffusion in an isospin-depedent transport ...

Classically isospinning Skyrmion solutions [PDF]
Physical Review D, 2014 We investigate how isospin affects the geometrical shape and energy of classical soliton solutions of topological charges $B=1-4,8$ in the Skyrme model. The novel approach in our work is that we study classically isospinning Skyrmions beyond the rigid-body approximation; that is, we explicitly allow the soliton solutions to deform and to break the ...

Phases of cold holographic QCD: Baryons, pions and rho mesons
SciPost Physics, 2023 We improve the holographic description of isospin-asymmetric baryonic matter within the Witten-Sakai-Sugimoto model by accounting for a realistic pion mass, computing the pion condensate dynamically, and including rho meson condensation by allowing the ...

Single particle potentials of asymmetric nuclear matter in different spin-isospin channels
, 2012 We investigate the neutron and proton single particle (s.p.) potentials of asymmetric nuclear matter and their isospin dependence in various spin-isospin $ST$ channels within the framework of the Brueckner-Hartree-Fock approach.

Isospin splittings of baryons [PDF]
AIP Conference Proceedings, 1998 We discuss the isospin-breaking mass differences among baryons, with particular attention in the charm sector to the $ _c^{+}- _c^0$, $ _c^{++}- _c^0$, and $ _c^+- _c^0$ splittings. Simple potential models cannot accommodate the trend of the available data on charm baryons. More precise measurements would offer the possibility of testing how well
