Using the functional renormalization group within the quark-meson model, this study demonstrates that the critical scaling region of the chiral phase transition systematically shrinks as chemical potential increases, with consistent results observed across both local potential approximations.
This paper demonstrates that helicity amplitudes for vector-boson decays to massless leptons, despite appearing to project only onto transverse polarization, encode complete information about all polarization states (including longitudinal) through little-group covariance, allowing the full covariant matrix to be reconstructed from any single polarization component using simple replacement rules in the massive spinor-helicity formalism.
This paper investigates the phenomenology of axion dark matter within the kinetic misalignment framework induced by generic PQ-breaking operators, analyzing their impact on relic density, cosmological constraints, and gravitational wave signals while identifying viable parameter spaces consistent with current experimental limits.
This paper investigates the global spin polarization of hyperons in heavy-ion collisions by incorporating quark spin correlation effects, utilizing experimental data to derive constraints and inequalities that could reveal evidence of such correlations at lower collision energies.
This paper demonstrates that directional detection using gas time-projection chambers can distinguish between standard halo dark matter and relativistic boosted populations (such as cosmic-ray upscattered or supernova-produced dark matter) with as few as approximately 20 recoil events by leveraging the unique anisotropic flux signatures of the latter.
This paper presents a comprehensive Bethe-Salpeter analysis of three-gluon decays in radially excited quarkonia and , demonstrating that their nodal wave function structures cause slow relativistic convergence in gluonic widths while enabling precise extraction of harmonic oscillator parameters that yield excellent agreement with experimental branching ratios.

This paper investigates fragmentation contributions to transverse nucleon spin observables in semi-inclusive deep-inelastic scattering at next-to-leading order within the collinear twist-3 factorization framework, confirming the validity of the formalism at the one-loop level and providing numerical predictions for HERMES and future EIC kinematics.
This paper employs QCD sum rules within a diquark model to systematically calculate the mass spectrum of hidden-charm singly-strange pentaquark states () with quantum numbers , $1{\frac{3}{2}}^-1{\frac{5}{2}}^-\Sigma_b\Xi_bJ/\psi \Sigma$ mass spectrum.
This paper presents updated constraints on the total neutrino mass and its hierarchy across various cosmological models using ACT DR6, DESI DR2, and DESY5 data, revealing that while dark energy evolution significantly influences the tightness of upper limits, the inverted hierarchy consistently yields weaker constraints than the degenerate hierarchy.
This paper demonstrates that within the most general formulation of gravity with independent metric and connection, a unique naturally light vector or scalar distortion field emerges as a dynamical degree of freedom, notably predicting a light scalar particle that mixes with the Higgs boson.
This paper systematically investigates the spectroscopic and decay properties of four triply heavy-flavor tetraquark systems using a nonrelativistic quark model, predicting compact ground-state masses between 5.2–5.5 GeV and 15.0–15.3 GeV that are unstable against strong rearrangement decays, while identifying specific narrow resonances and proposing experimental search channels in , , and modes.
This paper presents a global fit of flavor anomalies in semileptonic rare -meson decays using a machine learning Monte Carlo algorithm to emulate non-Gaussian likelihood landscapes, demonstrating that a specific scenario involving second-third generation quark mixing and independent four-fermion operator coefficients provides the best agreement with experimental data.
This paper proposes that quantum sensors can detect bursts of ultralight bosonic fields emitted during violent astrophysical events, thereby establishing a new multimessenger astronomy channel that remains viable even when accounting for matter screening effects.
This study utilizes an extended Integrated HydroKinetic Model to analyze light-hadron production in Au+Au collisions at RHIC Beam-Energy-Scan energies, demonstrating that both crossover and first-order phase transition equations of state can similarly describe soft particle spectra when parameters are adjusted, with the most significant distinctions appearing in proton and kaon yields at the lowest energy of 7.7 GeV.
This paper demonstrates that the Qwen2.5 Large Language Model, when combined with connector networks to form a "Lightcone LLM," can effectively analyze and generate 3D cosmological maps from SKA data, outperforming standard initialization methods and matching dedicated networks of similar size for tasks like parameter regression and lightcone generation.
This paper investigates how gravitational lensing in Hu-Sawicki f(R) gravity modifies neutrino oscillation phases and flavor transition probabilities, demonstrating that these effects depend on the model parameter, neutrino mass hierarchy, and absolute mass, thereby offering a novel method to test modified gravity and constrain neutrino parameters.
This paper proposes a minimal clockwork axion model with three scalar fields that generates two distinct stochastic gravitational wave signals—one in the nano-hertz range detectable by Pulsar Timing Arrays and another in the milli-hertz range observable by space-based interferometers like LISA, Taiji, and TianQin—while satisfying constraints from astrophysical and cosmological observations and explaining the QCD axion dark matter relic density.
This paper proposes a novel mechanism for generating high-frequency gravitational waves at approximately $10^{10}$ Hz through gravitational transition radiation, where particles emit gravitons as their masses change while traversing expanding bubble walls during first-order phase transitions in the early Universe.
This paper investigates fermionic dark matter in the scotogenic model within a low reheating temperature cosmology, demonstrating that entropy injection relaxes relic density constraints and that next-generation direct detection and charged lepton flavor violation experiments can effectively probe the resulting expanded parameter space.
