Delineating neutral and charged mesons in magnetic fields

Using a non-relativistic quark model with a harmonic oscillator potential, this paper investigates how neutral and charged mesons behave in magnetic fields across weak to strong regimes, highlighting distinct differences in their transverse dynamics and demonstrating how zero-point energy stabilizes high-spin charged mesons by canceling orbital Zeeman effects.

Charge radii of Sn isotopes in the relativistic mean field approximation

This paper investigates the kink in the charge radii of Sn isotopes around $N=82$ using the relativistic mean-field framework, revealing that while the small components of Dirac spinors for neutron states near the Fermi level significantly influence the proton central potential and contribute to the kink, they alone are insufficient to fully explain its observed magnitude.

Exact expectation values in a boost-invariant fluid of Dirac fermions with finite spin density

This paper presents an exact analytical and numerical study of a boost-invariant, out-of-equilibrium fluid of non-interacting Dirac fermions with finite spin potential, deriving explicit expressions for thermodynamic quantities and demonstrating that non-vanishing spin polarization in such free systems arises solely from the spin potential while shear-induced polarization and the spin Hall effect are absent.

Testing Scalar Field Self-Dualities in d=2 using a Variational Method

This paper quantitatively evaluates saddle-point expansion methods for testing self-dualities in 1+1 dimensional critical scalar $\phi^4$ theory, finding that while they accurately predict free energy, they deviate by approximately 25% from the peak location of the correlation length.

Charged-current quasielastic-like neutrino scattering from $^{12}$C in the coherent density fluctuation model with two-nucleon emission

This paper calculates charged-current quasielastic-like neutrino and antineutrino scattering cross-sections on $^{12}$C using the coherent density fluctuation model with a relativistic effective mass and two-nucleon emission, providing predictions for accelerator experiments like MiniBooNE, T2K, and MINERvA while analyzing the axial form factor $C^A_5(0)$ and momentum transfer dependencies.

Isospin-symmetry violation -- kaons and beyond (ISO-BREAK 25: summary and outlook)

This paper summarizes the ISO-BREAK 25 workshop held in Kielce in October 2025, which reviewed the current status of isospin-symmetry breaking observed by NA61/SHINE in nucleus-nucleus collisions, discussed its confirmation by other experiments, and outlined future experimental and theoretical priorities to explain this phenomenon.

Sensitivity of the $^{3,4}$He($K^-$, $\pi^0$) production ratio to the $\Lambda$ binding energy of $^3_\Lambda$H

Systematic study of flow of protons and light clusters in intermediate-energy heavy-ion collisions with momentum-dependent potentials

This study utilizes the PHQMD approach with a novel momentum-dependent potential to demonstrate that a soft, momentum-dependent nuclear equation of state best reproduces experimental flow data for protons and light clusters in intermediate-energy heavy-ion collisions, while also revealing distinct flow signatures that can help discriminate between different cluster formation mechanisms.

Valence quark-stopping and gluon junction-stopping scenarios in electron-nucleus collisions at the forthcoming Electron-Ion Collider: Which one is correct?

Using a multi-source thermal model, this paper argues that the valence quark-stopping scenario is more suitable than the gluon junction scenario for explaining baryon number transport in high-energy collisions, a conclusion that can be further validated by future electron-nucleus collision experiments at the Electron-Ion Collider.

Probing nuclear structure with the Balitsky-Kovchegov equation in full impact-parameter dependence

This paper extends the solution of the Balitsky-Kovchegov equation with full impact-parameter dependence to nuclear targets, providing predictions for key processes like deep-inelastic scattering and diffractive vector meson production to investigate gluon saturation and nuclear structure effects relevant for future facilities like the EIC and current LHC studies.
