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 demonstrates that spacetime curvature in and black hole backgrounds induces an effective magnetic field and chiral chemical potential for Dirac fermions, driving asymmetric real-time transport and entanglement dynamics confined within inhomogeneous Lieb-Robinson cones that are diagnostic of curvature and horizon effects.
This paper derives a dispersion integral representation of the Heisenberg-Euler QED effective lagrangian using Faddeev's quantum dilogarithm as a generalized Borel kernel, expressing its nonperturbative imaginary part via the quantum dilogarithm and its real part through a duality manifestation involving both the quantum dilogarithm and its modular dual.
This paper proposes a method to detect weak Lorentz-violating backgrounds in noncentrosymmetric crystals by measuring a distinct -periodic angular modulation in the nonlinear shift photocurrent, which arises from momentum-odd corrections to the Bloch Hamiltonian and offers sensitivity to coupling strengths as low as .
This paper presents a Palatini Supergravity model of induced-gravity Higgs inflation that is consistent with ACT DR6 data, successfully generates the parameter and non-thermal leptogenesis within a B-L MSSM extension, and predicts a split SUSY scenario with a PeV-scale gravitino mass compatible with LHC Higgs mass constraints.
This paper demonstrates that the DUNE-PRISM technique, which utilizes measurements at multiple off-axis angles to mitigate flux and cross-section systematic uncertainties, significantly restores the sensitivity of the DUNE experiment to new physics scenarios like non-unitarity and sterile neutrinos in the electron and muon sectors, while providing high-statistics flux data for future analyses.
The paper introduces SubTropica, a Mathematica package that utilizes tropical geometry to symbolically integrate multi-polylogarithmic integrals like Feynman diagrams, alongside its independent HyperIntica engine and an AI-driven online library for cataloging and retrieving physics results.
This paper demonstrates that the sensitivity of future long-baseline neutrino experiments like DUNE and T2HK to leptonic CP violation is significantly degraded by model-dependent cross-section assumptions, but this loss can be largely recovered by incorporating precise, data-driven cross-section measurements from the proposed SCOPE experiment.
This paper addresses limitations in existing resonant anomaly detection methods by introducing new simulated signal benchmarks and a comprehensive "kitchen sink" observable set combining Energy Flow Polynomials and subjettiness variables, demonstrating that this approach offers superior sensitivity across diverse signal types while an attribute bagging variant significantly reduces training costs with comparable performance.
This paper investigates how two distinct formalisms for modeling neutrino decoherence—one defined in the matter mass eigenstate basis and the other in the vacuum mass eigenstate basis—yield divergent oscillation probabilities and experimental sensitivities for future long-baseline experiments like DUNE and P2SO, particularly when decoherence parameters are large or matter effects are significant.
This paper demonstrates that while relativistic effects in the Fourier-space galaxy power spectrum exhibit strong degeneracies among different k-essence models, the angular power spectrum significantly amplifies these effects—particularly for tachyon fields—making it a more robust probe for detecting non-standard dark energy and highlighting the necessity of full relativistic modeling in upcoming horizon-scale surveys.
