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 proposes a unified formalism using Resonant Spin-Flavor Precession of GeV-scale neutrinos from solar flares and supernovae to distinguish between Dirac and Majorana neutrinos and probe magnetic moments down to , overcoming previous constraints by shifting resonance conditions to regions with specific magnetic field configurations.
This paper investigates a two-component dark matter model with symmetry, demonstrating that the requirement to reproduce the observed relic abundance naturally links a tiny Yukawa coupling to a large symmetry-breaking scale, thereby driving the portal interaction for scalar dark matter production into an ultra-feeble regime dominated by freeze-in dynamics.
This paper introduces a thermodynamic scaling framework for QCD enthalpy that defines an anomalous thermal dimension, , to successfully characterize the deconfinement crossover and link quantum scale anomalies to information-geometric curvature, as validated by Lattice QCD data.
This paper re-evaluates neutrino fluxes from a 10 TeV muon collider using the latest design, finding significantly higher fluxes than previously estimated and identifying substantial opportunities for QCD, electroweak, and new physics research through neutrino interactions in forward detectors.
This paper introduces the MINT simulation to characterize the intense forward neutrino flux and its secondary particles at a 10 TeV muon collider, demonstrating that a 5 km distant detector could observe approximately interactions annually while enabling searches for beyond-the-Standard-Model physics like heavy neutral leptons.
This paper demonstrates that Lorentz-equivariant transformers, when optimized for inference efficiency, outperform standard transformers in large-size jet and flavor tagging tasks whenever geometric features are relevant, offering valuable insights for developing foundation models for LHC data.
Using a field-theoretic approach, this paper demonstrates that compact binaries radiate angular momentum such that each emitted graviton carries approximately while scalar and dark photon quanta carry approximately , a result that holds for both elliptical and hyperbolic orbits and can be determined from orbital evolution despite the impossibility of a gauge-invariant decomposition into spin and orbital components.
This paper investigates the phenomenology of a complex scoto-singlet model that explains radiative neutrino masses and fermionic dark matter, identifying viable parameter spaces near Higgs resonances and coannihilation regions that are largely inaccessible to direct detection but potentially probeable via monojet searches and long-lived charged scalar signatures at colliders.
This paper uses direct N-body simulations and a semi-analytic framework to demonstrate that while the mass of ejected free-floating planets has negligible impact on their velocities, the mass and eccentricity of the giant perturber critically determine the ejection timescale and the high-velocity tail of the distribution, thereby shaping the observable microlensing signatures for upcoming missions like Roman and Euclid.
This paper presents a method for solving the Discretized Light-Cone Quantization Hamiltonian in 2D theory by incorporating perturbative zero-mode corrections, which significantly accelerates numerical convergence and reduces computational costs to achieve a precise critical coupling of using a much smaller basis space.
