Evidence for Multimodal Superfluidity of Neutrons

This paper presents theoretical and experimental evidence for a new phase of matter called multimodal superfluidity in neutron-rich systems, characterized by the coexistence of s-wave pairs, p-wave entangled double pairs, and quartets, which is predicted to occur in various fermionic systems and has significant implications for the structure and dynamics of neutron star crusts.

Axial-vector neutral-current measurements in coherent elastic neutrino-nucleus scattering experiments

This paper identifies fluorine-based compounds, particularly octafluoropropane, as optimal targets for measuring subleading axial-vector contributions in coherent elastic neutrino-nucleus scattering, demonstrating that such experiments could determine the axial coupling at the 10%\sim 10\% level and probe spin-dependent new physics.

Exploring TΥΥT_{ΥΥ} tetraquark candidates in a coupled-channels formalism

Using a coupled-channels framework derived from a constituent quark model, this study predicts a rich spectrum of resonant and virtual TbbbˉbˉT_{bb\bar{b}\bar{b}} tetraquark candidates exhibiting heavy-quark spin symmetry multiplets, with specific guidance provided for their experimental detection through characteristic decay patterns and widths.

Effects of isovector spin-orbit interaction on the charge-weak form factor difference in 48^{48}Ca, 208^{208}Pb, 90^{90}Zr and 62^{62}Ni

This study demonstrates that the charge-weak form factor difference in 48^{48}Ca and 90^{90}Zr is highly sensitive to the isovector spin-orbit interaction due to specific shell structures, whereas 208^{208}Pb and 62^{62}Ni remain insensitive, thereby guiding a strategic approach to use parity-violating electron scattering on these distinct nuclei to separately constrain the isovector spin-orbit strength and the symmetry energy slope.

A compendium of cold-nuclear matter baseline predictions in light-ion collisions

This paper presents comprehensive perturbative QCD baseline predictions for cold nuclear matter effects in light-ion collisions at LHC energies, demonstrating that while these effects induce significant suppressions with large uncertainties, specific multi-cross-section ratios can effectively cancel these uncertainties to enhance the sensitivity to quark-gluon plasma signatures.

Kaon-deuteron femtoscopy from unitarized chiral interactions

This paper presents a theoretical study using unitarized chiral interactions to calculate KdK^-d and K+dK^+d correlation functions, demonstrating that the inclusion of strong scattering effects—particularly the subthreshold Λ(1405)\Lambda(1405) resonance for KK^- and the mildly repulsive force for K+K^+—successfully reproduces ALICE experimental data and validates femtoscopy as a powerful tool for probing strangeness-related hadronic interactions.
