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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper introduces a reinforcement learning method that efficiently identifies Standard Model Effective Field Theory (SMEFT) operators capable of explaining particle physics anomalies, such as the CDF W-mass discrepancy, by overcoming the limitations of human bias and the vast complexity of the operator space.
This paper proposes that the LZ230616 high-recoil candidate is caused by transition magnetic-dipole dark matter, where an endothermic nuclear recoil is followed by a delayed photon, and demonstrates that this model can explain the event while satisfying thermal abundance constraints and remaining consistent with various direct and indirect detection limits.
The paper argues that resolving the mismatch of anomalies across different geometries dual to the same CFT in extra-dimensional AdS theories requires adding topological terms or bulk fermions to ensure anomaly consistency by flowing IR-localized anomalies into the UV region.
This paper investigates whether the isolated nuclear-recoil event reported by the LUX-ZEPLIN (LZ) collaboration could originate from elastic neutrino-nucleus scattering, concluding that kinematic constraints, the recoil spectrum, and existing limits rule out this explanation across all considered Standard Model and beyond scenarios, including exotic neutrino fluxes from dark matter and primordial black holes.
This paper proposes a novel dark matter detection concept based on gravitational focusing by the Sun and Earth, which amplifies the flux of streaming dark matter into transient, daily recurring signals lasting approximately 10 seconds, offering a unique opportunity for identifying invisible matter.
This paper introduces generalized thermodynamic relations into relativistic perfect spin hydrodynamics to ensure a consistent treatment of spin degrees of freedom based on microscopic calculations, thereby establishing a foundation for unifying different formulations and incorporating dissipative corrections.
This paper systematically investigates a symmetric model featuring two scalar dark matter components that undergo co-annihilation, analyzing their viability as WIMP or pFIMP candidates within the framework while confronting the allowed parameter space against current direct and indirect detection constraints.
This paper proposes a gauge extension of the Standard Model where a specific set of neutral right-handed fermions simultaneously ensures gauge anomaly cancellation, generates light neutrino masses via a scotogenic mechanism, and provides a stable dark matter candidate consistent with relic abundance constraints.
SageNet is a deep learning framework that utilizes Long Short-Term Memory networks to emulate stiff-amplified inflationary gravitational wave spectra with high accuracy and a -fold speedup over traditional numerical solvers, thereby enabling efficient Bayesian inference for extended cosmological models.
This paper proposes a mechanism for forming early supermassive black hole seeds via "not-quite-primordial" black holes, where enhanced but sub-critical density fluctuations lead to direct collapse of baryons in early halos, successfully explaining high-redshift JWST observations while remaining consistent with CMB and reionization constraints.
