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 that ultraheavy nuclei could constitute the highest-energy cosmic rays, offering a consistent explanation for the Amaterasu particle, constraints on source energy generation rates, and the spectral tension between Telescope Array and Pierre Auger Observatory data, while predicting distinct shower maximum depths for future experimental verification.
This paper introduces a novel inclusive-tagging scheme based on an asymptotically recursive vector sequence that enables the first indirect reconstruction of multiple undetected particles, such as neutrinos, in collider experiments, thereby significantly enhancing the precision of Standard Model measurements and the search for new physics.
This paper proposes a gauge extension of the Standard Model featuring a scalar leptoquark, new fermions, and inert scalars to simultaneously explain -meson flavor anomalies, generate neutrino masses, and provide a dark matter candidate, while analyzing constraints from transitions and predicting observables for decays.
This paper calculates the effects of quantum decoherence on maximally entangled fermion pairs at colliders by identifying the relevant Kraus operators with integrated Altarelli-Parisi splitting functions, addressing a factor often neglected in recent LHC measurements of top-quark spin entanglement.
This paper provides a model-independent re-evaluation of cosmological constraints on photophilic axion-like particles with masses below 10 GeV and lifetimes under seconds by incorporating rare hadronic decays and reheating temperature dependencies, revealing extended bounds and potential parameter space to resolve tensions in and deuterium abundance.
This paper presents the first complete analytical derivation of one-loop electroweak and QED corrections to leptonic decays, demonstrating that incorporating these radiative effects resolves the reported violation of CKM unitarity in the second column and highlights the need for improved lattice simulations including QED corrections to further confirm the Standard Model.
By phenomenologically adjusting a holographic D3/D7 system to describe a deconfined yet massive quark phase, this study demonstrates that such matter can form a stiff equation of state capable of supporting stable hybrid stars with quark cores up to 2 solar masses, thereby offering a viable holographic framework for exploring the interiors of heavy compact stars.
This paper proposes that five-dimensional primordial rotating black holes, whose lifetimes are significantly extended by the "dark dimension" scenario and the memory burden effect, can survive to the present day and potentially account for all of the universe's dark matter.
This paper introduces a novel, model-agnostic method using constrained Gaussian-process bridges to generate stable, causal, and thermodynamically consistent nonparametric priors for neutron-star equation-of-state inference, enabling the flexible integration of diverse theoretical constraints without requiring iterative shooting.
This paper demonstrates that the proposed lunar-based Crater Interferometry Gravitational-wave Observatory (CIGO) and its upgraded tetrahedral configuration (TCIGO) can significantly outperform existing space-based missions like TianQin and LISA in sky map resolution for monochromatic sources in the 0.1–10 Hz band, provided lunar noise is effectively mitigated.
