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 investigates how photon-axion conversion in the strong gravitational fields of rotating Kerr black holes, particularly around M87*, causes observable dimming of photon spectral luminosity in X-ray and gamma-ray bands, offering a potential method for future high-resolution telescopes to constrain axion properties.
The CONUS collaboration reports a observation of coherent elastic neutrino-nucleus scattering at the Leibstadt reactor and utilizes combined datasets from Brokdorf and Leibstadt to establish new, improved constraints on neutrino magnetic moments, millicharges, non-standard interactions, light new mediators, and the Weinberg angle, thereby advancing the search for physics within and beyond the Standard Model.
This paper develops a bottom-up open effective field theory for non-Abelian gauge theories within the Schwinger-Keldysh formalism by explicitly retaining slow environmental color variables to construct a local, gauge-covariant Markov embedding that naturally recovers hard thermal loop responses and provides a systematic framework for studying color transport, memory effects, and fluctuation-dissipation in non-Abelian plasmas.
This paper investigates the implications of the KSVZ axion on the electroweak Cho-Maison monopole by deriving the equations of motion and numerically analyzing how the axion-photon coupling alters the monopole's mass, electromagnetic charges, and potential energy.
This paper investigates the out-of-equilibrium evolution of a superfluid in expanding backgrounds relevant to heavy-ion collisions and cosmology, identifying a novel "attractor time" that characterizes the transition to hydrodynamic attractors and revealing a unique nonlinear regime of constant anisotropy in Gubser flow alongside late-time condensate-dominated behavior in FLRW spacetime.
This paper proposes two novel multilepton signatures arising from exotic Higgs decays into a light pseudoscalar that subsequently decays into an electron-muon pair, demonstrating that collider-based searches in the Type-III Two-Higgs-doublet model can provide stronger constraints on electron-muon flavor violation than current low-energy precision measurements.
This paper establishes the universality of the chiral soliton lattice (ChSL) as a robust low-energy feature of QCD coupled to electromagnetism, demonstrating its stability against higher-order corrections and deriving the exact analytical spectrum of fermionic excitations to characterize its interaction with quark matter.
This paper proposes a novel method to constrain axion-like particle parameters by demonstrating that resonant axion-photon conversion in a primordial helical magnetic field generates a detectable circular polarization (-mode) signal in the cosmic microwave background, allowing future observations like CLASS to probe previously unconstrained mass and coupling ranges.
This paper demonstrates that space-based gravitational wave detectors, specifically the Taiji mission, can constrain the Higgs cubic and quartic self-couplings by inferring macroscopic parameters of a first-order electroweak phase transition from the stochastic gravitational wave background, even in the presence of instrumental noise, astrophysical foregrounds, and parameter degeneracies.
This paper proposes that dark matter in the GeV mass range can resolve small-scale cosmological challenges through a "super-resonance" mechanism combining narrow resonance and Sommerfeld effects, which necessitates the use of coupled Boltzmann equations to accurately calculate its relic density while satisfying observational constraints.
