This paper demonstrates that while varying the top Yukawa coupling within experimentally allowed ranges significantly alters the total cross-section for triple Higgs production at the LHC, it has minimal impact on the invariant mass distribution of the three-Higgs system and other global observables.
This paper presents a unified and self-consistent framework to refine constraints on superluminal Lorentz Invariance Violation using the 220 PeV KM3NeT neutrino event, correcting previous inaccuracies in decay-width expressions, threshold effects, and cosmological propagation while validating the use of survival-probability approximations.
Using the covariant four-dimensional Bethe-Salpeter equation with an infrared-finite QCD running charge, this study determines a scale-dependent effective charm quark mass (ranging from 1.1 to 1.5 GeV) that successfully reproduces experimental leptonic decay constants for excited charmonium states with unprecedented theoretical precision.
This paper demonstrates that the Japan Proton Accelerator Research Complex (J-PARC) offers optimal conditions for Coherent Elastic Neutrino-Nucleus Scattering (CENS) experiments, showing that current and developing detector technologies can achieve high-statistics measurements with significant sensitivity to various particle physics scenarios within the next few years.
This paper reinterprets classic radiochemical solar-neutrino measurements as rate meters to establish stringent 90% upper limits on fermionic dark matter absorption, deriving constraints on the effective interaction scale that are complementary to xenon-based and collider searches.
This paper proposes a quantum-gravitational framework based on Schwarzian theory and ensemble averaging to resolve the cosmological constant problem by deriving the observed dark energy density and equation of state from the ensemble average of time-reparametrization modes.
This paper investigates the isentropic thermodynamics of the hadron-quark mixed phase using a two-phase model with a PNJL quark sector, revealing how entropy per baryon, vector interactions, isospin asymmetry, and hyperon population influence the phase diagram, temperature evolution, speed of sound, and deconfinement onset.
This paper proposes that a minimal dark scalar with a mass of approximately 9.40 GeV, which shares high- fragmentation scaling with NRQCD color-octet production, can simultaneously explain the anomalous high- plateau in nuclear modification factors, the vanishing elliptic flow, and the quarkonium polarization puzzle in heavy-ion collisions while evading historical low- constraints.
This paper reviews the progress of functional QCD over the past decade in describing the phase structure of QCD, with a primary focus on predicting new phases and their experimental signatures at high densities () while addressing technical strategies, systematic errors, and validation against lattice QCD.
This paper demonstrates that standard strong-field QED models fail to accurately predict angle-, spin-, and polarization-resolved distributions because they incorrectly treat photon emission as an instantaneous local event, and it proposes a new physically consistent model that integrates over the finite formation region to reveal significant deviations in polarization and helicity patterns with major implications for both laboratory experiments and astrophysical observations.
This paper employs dispersion theory to analyze the isovector vector form factors of , , , and mesons at low energies by integrating chiral and heavy-quark symmetry constraints with model-independent resonant pion-pion rescattering, while specifically addressing anomalous thresholds to extract the resonance couplings to these heavy mesons.
This paper presents a comprehensive effective field theory pipeline that connects baryon number-violating new physics to low-energy hadronic observables by systematically matching Standard Model EFT operators up to dimension nine to Low-Energy EFT and chiral perturbation theory, thereby enabling a model-independent analysis that incorporates higher-dimensional operators and a broader class of ultraviolet completions than previously possible.
This paper introduces a self-supervised, transformer-based approach that generates oracle trajectories by scrambling and unscrambling mathematical expressions to achieve near-perfect symbolic simplification in high-energy physics tasks, significantly outperforming prior reinforcement learning and regression methods.
This paper proposes a unified framework where ultra-slow-roll inflation simultaneously generates primordial black hole dark matter, the baryon asymmetry via spontaneous baryogenesis, and a detectable stochastic gravitational wave background, establishing a predictive correlation between these phenomena that can be distinguished by future gravitational wave observatories like LISA, DECIGO, and the Einstein Telescope.
This paper demonstrates that perturbative reheating following inflation systematically suppresses the gravitational wave signals from cosmological phase transitions compared to standard radiation-dominated scenarios, while introducing characteristic spectral features that could serve as distinctive signatures of the modified expansion history.
This paper proposes a machine-learning-inspired extension of the Simplified Template Cross Section (STXS) framework that uses supervised classifiers to define simple, linear phase-space boundaries for production, demonstrating that these optimized regions systematically outperform standard STXS bins in sensitivity to SMEFT effects while preserving experimental transparency.
This paper demonstrates that while the effective-field-theory description of vector Higgs-portal dark matter is largely excluded by direct detection limits, a renormalizable UV-complete model featuring an additional gauged symmetry and a dark Higgs scalar can reopen viable parameter space by introducing a second resonant annihilation channel that significantly weakens experimental constraints.
This paper employs both machine learning techniques and an extended analytical mass formula to predict the mass spectra of fully-heavy baryons and exotic pentaquarks, offering complementary insights that align with existing experimental data and guide future searches for unobserved states.
This paper demonstrates that consistent quantum tomography of and decays requires the subtraction of higher-order corrections to ensure physical spin density operators, while also highlighting the potential to observe parity-violating effects in .
The paper proposes "Unified Flavor," a framework where hierarchical Yukawa couplings and CP violation emerge from TeV-scale vectorlike fermion chains on a -lattice governed by a single flavon, successfully reproducing quark and lepton mass spectra while simultaneously addressing flavor constraints, strong CP, and offering testable predictions for future experiments.
