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 presents an improved formula for the Wigner function and spin polarization of fermions emitted from a decoupling relativistic fluid by introducing a new expansion method that captures geometric dependencies in the spin-shear term and naturally justifies the isothermal condition without prior assumptions.
This study demonstrates that dark matter subhalos with steep inner density profiles are significantly more detectable via strong gravitational lensing than standard NFW subhalos, remaining observable even in complex lens models, which offers a powerful method for testing dark matter microphysics and distinguishing between Cold Dark Matter and alternative models.
This paper identifies as the minimal continuous symmetry required to protect TeV-scale new physics from flavor constraints, demonstrating that this framework can reproduce observed fermion hierarchies with minimal symmetry breaking while significantly expanding the viable parameter space for collider-accessible scenarios beyond standard Minimal Flavor Violation.
This paper introduces BBNet, a fast and accurate deep learning emulator that replaces computationally expensive Big-Bang Nucleosynthesis solvers with a residual multi-head neural network capable of predicting primordial light element abundances in milliseconds while maintaining high precision across extended cosmological models.
This paper develops a general effective field theory framework to systematically identify renormalizable ultraviolet-complete models that enable large neutrino-dark matter interactions consistent with theoretical and experimental constraints, including specific realizations in scotogenic and seesaw-based neutrino mass models.
This paper demonstrates that the TRIDENT neutrino telescope will surpass the thermal freeze-out benchmark for dark matter annihilation in the Galactic Centre by leveraging cascade events and accounting for a previously overlooked background of Galactic neutrinos, thereby probing untested regions of parameter space.
This paper demonstrates that transverse momentum conservation is the dominant mechanism causing the breakdown of azimuthal correlation factorization in small systems, quantitatively explaining CMS p-Pb data and establishing a sign rule where deviations from unity alternate based on harmonic order, thereby necessitating the subtraction of this kinematic effect to isolate genuine flow fluctuations.
This paper compiles and recomputes macroscopic dark matter constraints to explicitly account for the dark matter fraction, enabling the mapping of these limits to extended mass functions and demonstrating that even the tails of such distributions can be severely constrained by macro interactions.
This paper presents an agnostic search strategy for single vector-like top partner production at a 3 TeV lepton collider using the recoil mass technique, demonstrating a discovery potential exceeding significance for masses at the lowest benchmarks when the coupling strength surpasses approximately 0.3 under realistic conditions including beam polarization and initial-state radiation.
This paper proposes an extended Two-Higgs Doublet Model with discrete symmetry and four-zero textures that naturally explains fermion mass hierarchies, suppresses flavor-changing neutral currents, incorporates a dark matter candidate, and simultaneously accommodates observed neutral resonance excesses while remaining consistent with LHC and lepton flavor violation constraints.
