Non-Abelian Dirac oscillator gains spin–isospin splitting
This research indicates that a covariant Dirac oscillator in external non-Abelian gauge fields can produce matrix-valued spin–isospin couplings and, in a planar background, an explicit isospin splitting.

Exact algebro-geometric solution obtained for the modified Camassa-Holm equation
This research indicates that an exact algebro-geometric solution of the modified Camassa-Holm equation can be derived from hyperelliptic curves and reconstructed through a Riemann-Hilbert problem and Baker-Akhiezer function.

Z4-symmetric scalar dark matter model shows enhanced co-scattering
This research indicates that a two-component scalar dark matter model with a remaining Z4 gauge symmetry can produce enhanced co-scattering and semi-annihilation under certain resonance conditions.

Neutral-kaon decays can show CP violation through detector-dependent effects
This research indicates that CP violation in decays to final states containing neutral kaons depends on an efficiency function that separates into the kaon energy spectrum and a detector-dependent factor, and that matter effects on kaon oscillations can significantly affect CP asymmetries.

Carroll-symmetric approach fixes leading light-transformed OPE terms
This research indicates that the leading operator product expansion term for light-transformed operators in flat-space holography can be fixed by accounting for the sub-leading term, and that a similar study can be started for shadow-transformed graviton correlators.

Interacting dark energy and dark matter models fit current cosmological data
This research indicates that interacting bosonic dark energy and fermionic dark matter models in Einstein scalar Gauss–Bonnet gravity are in good agreement with current data and remain close to the standard ΛCDM expansion history while allowing small deviations.

Adjoint QCD2 can exhibit supersymmetry at special fermion masses
This research indicates that one-dimensional SU(N) gauge theories with adjoint Majorana fermions can have supersymmetry at special masses, and that some related models also have supersymmetric sectors.
