Minimal Quark-Lepton Complementarity from a Rigid Deformation of Tri-Bimaximal Mixing

This paper proposes a minimal, parameter-free model of quark-lepton complementarity where a rigid, unitary rotation of the tri-bimaximal mixing matrix about the axis (2,1,2)T/3(2,1,2)^T/3 by an angle fixed to the Cabibbo angle successfully predicts current neutrino oscillation parameters, including a near-maximal atmospheric angle and a near-CP-conserving Dirac phase, while ranking as the simplest viable candidate among thousands of alternatives.

Tracing Vacuum Hadronization with Conserved Currents

This paper demonstrates that color triality constraints on vacuum hadronization allow the simultaneous measurement of conserved current flows (electric charge, baryon number, and strangeness) in jets to directly probe nonperturbative QCD parameters, specifically the diquark-to-quark production ratio and strange-to-light pair-production ratio, while satisfying the Gell-Mann–Nishijima relation.

Kerr Quasinormal Modes without Variable Separation: A Two-Dimensional Hyperboloidal Teukolsky Solver with Physics-Informed Neural Networks

This paper demonstrates that physics-informed neural networks can accurately solve the two-dimensional, non-separable Teukolsky equation for Kerr black hole quasinormal modes, offering a flexible alternative to traditional spectral methods that avoids variable separation and maintains high precision even in the near-extremal regime.

Instability diagram of the massive gauge quantum fields around the nonlinear massive classical wave solution

This paper analyzes the time dynamics of quantum fluctuations in massive gauge fields around a nonlinear classical wave solution, employing Hill's equation and Floquet theory to demonstrate that while transverse polarization modes exhibit narrow parametric-resonance bands, longitudinal modes display broader instability regions driven by both parametric and spinodal mechanisms, with distinct low-momentum instabilities identified for the WW boson compared to the ZZ sector.

Skewness dependence of the pion and kaon generalized parton distributions

Using the covariant Nambu-Jona-Lasinio model with Schwinger proper-time regularization, this study investigates the skewness and momentum transfer dependence of pion and kaon generalized parton distributions, finding that valence-quark distributions are strongly suppressed by increasing momentum transfer and skewness (especially at lower scales) while gluon distributions show weak dependence on both, with results at specific scales aligning well with experimental data, global JAM analyses, and lattice-QCD calculations.

Negative diffusion in the Functional Renormalization Group flow for the Quark-Diquark Model

This paper identifies negative diffusion as the intrinsic cause of numerical instabilities in the Functional Renormalization Group flow of the Quark-Diquark Model at low temperatures and high chemical potentials, and proposes a hyperdiffusion-based regularization scheme to stabilize the flow for reliable studies of color superconductivity and inhomogeneous phases.

Non-Minimally Coupled Warm Inflation in the Defining Frame

This paper investigates warm inflation in non-minimally coupled scalar-tensor gravity within the defining frame, revealing that modified-gravity effects can suppress dissipation and allow quantum perturbations to dominate over thermal fluctuations even in high-temperature regimes, while providing benchmark models consistent with current CMB constraints.

Correspondence between hydrodynamic frames, transport coefficients, and hydrodynamic modes in relativistic fluids

This paper demonstrates that while the choice of hydrodynamic frame (Eckart vs. Landau--Lifshitz) significantly alters the numerical values of transport coefficients like thermal conductivity, physical observables such as sound attenuation remain invariant, underscoring the necessity of specifying the frame when comparing results across different theoretical and experimental contexts.
