Hep-Ph explores the fundamental forces that govern how particles interact and behave at the smallest scales imaginable. This field bridges the gap between theoretical predictions and experimental reality, helping scientists understand the building blocks of our universe without getting lost in complex mathematics. Whether investigating the Higgs boson or searching for new physics beyond current models, these studies push the boundaries of human knowledge about matter and energy.

This paper introduces a reformulated electric basis and a local Krylov subspace truncation strategy for pure SU() lattice gauge theories, demonstrating that these efficient Hamiltonians remain consistent with traditional calculations at small couplings while reducing the computational resources required for quantum time evolution by 17–19 orders of magnitude.
The paper proposes CARAMEL, a compact and scalable axion dark matter detection strategy that utilizes electro-optic crystals and externally injected radio-frequency power to amplify and optically read out axion-induced ellipticity modulations in the 0.5–50 GHz range, thereby enabling high-sensitivity searches across the preferred post-inflationary Peccei–Quinn axion mass parameter space.
This study demonstrates that incorporating General Relativistic effects into core-collapse supernova models significantly enhances the efficiency of the p-process, enabling a sufficiently massive progenitor to reproduce the full range of solar system -nuclide abundances up to Pd, whereas Newtonian calculations fail to do so.
This study employs a comprehensive Bayesian analysis integrating terrestrial nuclear physics data with astrophysical observations from PSR J0437+4715, PSR J0614+3329, and GW170817 to constrain the neutron star equation of state, ultimately favoring the Skyrme model and yielding precise determinations of symmetry energy parameters and the radius and tidal deformability of a 1.4 solar mass neutron star.
This paper demonstrates that a radiative neutrino mass model with TeV-scale scalar leptoquarks can resolve the electron anomaly under inverted neutrino mass ordering while predicting negligible effects on the muon and testable lepton-flavor-violating tau decay rates, all while satisfying stringent constraints from and neutrino oscillation data.
This paper systematically investigates baryon-number-violating nucleon decays involving a light scalar within the Standard Model Effective Field Theory framework, deriving stringent constraints from experimental data, predicting distinctive three-body decay signatures and dinucleon transitions, and proposing ultraviolet-complete models to explain the underlying physics.
This study utilizes molecular dynamics and density functional theory to investigate defect formation in NaI crystals induced by dark matter collisions, proposing that the resulting new electronic states within the band gap could serve as a novel detection channel for dark matter searches.
This paper proposes a unified framework demonstrating that early causal tensor sources, such as phase transitions and topological defects, generate a universal tensor power spectrum that produces a distinct, small-scale-enhanced -mode signature in the cosmic microwave background, differentiating them from the scale-invariant predictions of inflation.
This paper presents the first application of the MiNLO method to QED NLO corrections in Drell-Yan processes, specifically addressing initial-state radiation for Z boson decays into neutrinos, proposing a modified formula to handle QED-specific challenges, and quantifying uncertainties as a foundational step toward integrating full electroweak effects into the MiNNLOPS framework.
This paper evaluates the validity of the Standard Model Effective Field Theory (SMEFT) versus the Higgs Effective Field Theory (HEFT) for Higgs pair production by comparing their predictions against "Loryon"-inspired UV-complete models, demonstrating that HEFT can offer a more accurate description than SMEFT in specific parameter regimes and highlighting di-Higgs measurements as a probe for non-linear electroweak dynamics.
