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 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 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.
This paper investigates the vacuum structure and phenomenology of a symmetric three Higgs doublet model with two inert scalar doublets, revealing new viable parameter space where two-component dark matter candidates contribute comparably to the observed relic density and offer distinctive experimental signatures.
This paper demonstrates that the Taiji space-based gravitational-wave detector can effectively probe the complex singlet extension of the Standard Model by performing Bayesian and Fisher-matrix analyses to constrain Higgs self-couplings through the detection of electroweak phase transition signals, thereby highlighting the complementarity between gravitational-wave observations and collider physics.
This paper investigates the parameter space for large CP violation in the complex two-Higgs-doublet model, revealing that Type-I scenarios predict eEDM values within next-generation experimental reach due to gauge-sector CPV, while Type-II models allow for nearly maximal Yukawa-sector CPV suppressed to negligible eEDM levels through destructive interference, alongside a newly identified "hidden CPV" phenomenon in the near-alignment limit that can be probed at future colliders.
This study utilizes Big Bang Nucleosynthesis abundances to constrain temperature-dependent CPT violation parametrized by an electron-positron mass asymmetry scaling as , establishing stringent limits on early-universe CPT violation that are inaccessible to zero-temperature laboratory experiments.
This paper motivates the use of quantum simulation to overcome the exponential computational scaling limitations of classical lattice field theory in studying dense matter and dynamical phenomena, while reviewing current theoretical, algorithmic, and hardware progress and outlining future challenges and opportunities.
This paper presents the first rigorous determination of the physical masses of electroweak vortex rings in the Standard Model, establishing values of 18.01 and 26.80 TeV for different winding numbers and revealing a self-stabilizing pinch mechanism driven by repulsive interactions and complex current distributions.
This paper introduces VLQBounds, a public Python framework that automates the confrontation of Vector-Like Quark models with LHC exclusion limits by interpolating machine-readable experimental grids to provide rapid, channel-by-channel 95% confidence-level verdicts for various production and decay scenarios.
