Cutoff-independent predictions from nuclear lattice effective field theory

This paper demonstrates that a minimal chiral nuclear force, constrained only in the $A \leq 3$ sector and utilizing a lattice-inspired absolute-momentum regulator, achieves remarkable cutoff independence and accurately reproduces binding energies up to $^{40}\text{Ca}$ without requiring complex many-body forces.

Rank-2 Electromagnetic Backgrounds and Angular Momentum Barriers in Gravitomagnetic Spin-Quadrupole Searches

This paper analyzes the angular momentum selection rules and identifies four dominant electromagnetic background barriers that constrain spectroscopic searches for gravitomagnetic spin-quadrupole coupling in highly charged ions, ultimately deriving the specific multi-isotope experimental topology required to isolate the gravitational signal and establishing a preliminary laboratory bound on the gyrogravitational ratio.

Interaction between nuclear clusters and superfluid phonons in the neutron-star inner crust

This paper employs nuclear density functional theory to derive a microscopic description of the interaction between nuclear clusters and superfluid phonons in the neutron-star inner crust, revealing a significantly smaller coupling constant than previous hydrodynamical estimates due to the suppression of phonon amplitude within the clusters.

Probing QCD instantons using jet correlation observables in proton-proton collisions at the LHC

This paper proposes jet correlation observables to unambiguously distinguish instanton-induced processes from perturbative QCD events in proton-proton collisions at the LHC, utilizing constraints derived from 2+1 flavor QCD calculations to guide future searches at the Electron-Ion Collider.

Exploring Particle Production and Thermal-Like Behavior through Quantum Entanglement

Bottomonium transport in a strongly coupled quark-gluon plasma

This paper presents a semiclassical transport approach combining lattice-constrained $T$-matrix interactions with viscous hydrodynamics to model bottomonium suppression and regeneration in Pb-Pb collisions, successfully describing centrality-dependent yields at the LHC while highlighting discrepancies at high transverse momenta due to enhanced reaction rates.

Determination of the Muon Lifetime in $^{76}$Se with the MONUMENT experiment

The MONUMENT collaboration determined the muon lifetime in $^{76}$Se with improved accuracy to be (135.1 $\pm$ 0.5) ns, a result that aligns with phenomenological calculations using unquenched axial-vector coupling and serves as a benchmark for neutrinoless double beta decay models.

Self-gravitating baryonic tubes supported by $\pi$- and $\omega$-mesons and its flat limit

This paper constructs self-gravitating, singularity-free baryonic tube solitons in an $SU(N)$ Einstein non-linear sigma model coupled to $\omega$-mesons, demonstrating that increasing the number of flavors enhances physical predictions by reducing binding energy despite increasing total energy.

Inclusive $J/ψ$ productions in pp collisions at $\sqrt{s}=$ 5.02, 7, and 13 TeV with the PACIAE model

This study utilizes the PACIAE 4.0 model, which incorporates both color-singlet and color-octet NRQCD contributions alongside cluster collapse and $b$-hadron decays, to successfully simulate inclusive $J/\psi$ production in proton-proton collisions at 5.02, 7, and 13 TeV and provide a quantitative analysis of the relative contributions and rescattering effects across various production mechanisms.

New Physics Searches via Beam Normal Spin Asymmetry in Bhabha Scattering

This paper investigates the sensitivity of the beam normal spin asymmetry in Bhabha scattering to beyond-the-Standard-Model mediators within the JLab polarized positron program, highlighting how the observable's unique zero crossing in the Standard Model provides a clean, background-free opportunity to significantly extend search ranges for scalar and vector new physics scenarios.
