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 establishes the current best constraints on the charge and mass of fermionic and bosonic millicharged particles by analyzing their Schwinger mechanism production in thunderstorms across Solar system planets, with the most stringent limits derived from Saturn's atmospheric observations.
This paper analyzes an inverse seesaw model with non-degenerate pseudo-Dirac heavy states governed by specific discrete flavor symmetries, finding that while current charged lepton flavor violation limits do not strongly constrain the parameter space compatible with observed lepton mixing, upcoming experiments like Mu3E, COMET, and Mu2e are expected to provide significant tests.
This paper presents a unified Froggatt-Nielsen effective theory with three right-handed neutrinos and complex coefficients that simultaneously explains fermion flavor hierarchies, neutrino masses, dark matter, and the baryon asymmetry of the Universe, demonstrating that successful thermal leptogenesis is viable in both freeze-in and freeze-out scenarios.
This paper demonstrates that for near-horizontal cosmic-ray air showers, the longitudinal development can be reconstructed by mapping the time dependence of the observed induced electric field to atmospheric slant depth, enabling the inference of key shower parameters such as from single observer measurements.
The paper proposes a novel nuclear interferometer utilizing the thorium-229 clock transition to detect ultra-light dark matter, offering enhanced sensitivity to variations in fundamental constants and the QCD sector that could complement and surpass existing terrestrial clock experiments.
This paper investigates the mass spectra and strong and radiative decay properties of high-lying and charmonium states around 4 GeV, incorporating unquenched effects to provide theoretical predictions that guide future experimental searches at facilities like BESIII, Belle II, LHCb, and STCF.
This paper employs the Lanczos algorithm to investigate Krylov complexity in the early universe as an open system across inflation, radiation, and matter domination epochs, revealing distinct dissipative behaviors, the similarity of complexity evolution across various inflationary potentials, and deriving new evolution equations for squeezing parameters via Meixner polynomials to demonstrate rapid decoherence-like effects.
This review examines the fundamental principles of thermal field theory in a background magnetic field, focusing on equilibrium systems to analyze bulk thermodynamic properties and real-time observables relevant to the thermo-magnetic QCD plasma in heavy-ion collisions.
This paper defends Large-Momentum Effective Theory (LaMET) against recent claims that it suffers from an unquantifiable inverse problem, arguing that physics-guided systematic extrapolation remains the most reliable method for estimating uncertainties in parton distribution calculations even when lattice data precision is suboptimal.
This paper demonstrates that local over-densities, such as experimental cavities, can significantly suppress the amplitude and gradient of quadratically coupled ultra-light scalar dark matter, thereby hindering detection efforts and relaxing existing constraints on such models, while also proposing a differential force measurement between cavities of different internal structures as a potential detection method.
