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 presents a comprehensive formulation for calculating the angular power spectrum of cosmic background photons from dark matter decay or annihilation, emphasizing the critical role of detector energy resolution, and applies this framework to observational data across infrared, optical, X-ray, and gamma-ray wavelengths.
This paper examines the color structure of two-loop gluon amplitudes in Yang-Mills theory using both color trace and structure constant bases to systematize relations between partial amplitudes.
This paper employs QCD sum rules to theoretically predict the ground-state masses of various hypothetical single-top baryons and mesons, finding that many of these states may exhibit weak binding or lie near constituent mass thresholds, thereby providing essential benchmarks for future experimental searches at the LHC and next-generation facilities.
This paper presents a combined analysis of dimension-6 and dimension-8 SMEFT operators using W-boson helicity fractions in top-quark decays, demonstrating that including dimension-8 contributions significantly alters the constraints on dimension-6 coefficients due to non-trivial correlations and the necessity of a consistent EFT expansion treatment.
This paper proposes a novel detection scheme for QCD axions in the to eV mass range by utilizing piezoelectric materials to generate a significantly enhanced axion-mediated force that induces resonant nuclear spin precession in a nearby sample.
This paper demonstrates that at higher temperatures, chiral plasma instability can generate strong magnetic fields even with small initial chiral imbalances, and reveals a novel mechanism where the chiral magnetic effect driven by density fluctuations causes significant Joule heating, potentially playing a critical role in the dynamics of supernovae and neutron star mergers.
This paper evaluates next-to-leading power contributions to slepton pair production at hadron colliders near threshold, demonstrating that these terms are significant compared to leading-power logarithmic corrections and revealing that existing calculations underestimate scale uncertainties for large slepton masses, with results also provided for a future 85 TeV FCC-hh machine.
This paper proposes two scenarios—graviton-to-photon conversion via the Gertsenshtein effect and binary PBH mergers—to constrain the abundance of memory-burdened primordial black holes, thereby excluding specific mass windows for sub- g PBH dark matter that would otherwise evade standard evaporation limits.
This paper validates a Long Short-Term Memory (LSTM) neural network approach that successfully identifies jet quenching in heavy-ion collisions by leveraging jet substructure and parton shower history, demonstrating robust performance even when accounting for detector effects and generalizing to untrained observables.
This paper proposes a model-independent method to detect CP violation in the heavy scalar sector at future muon colliders by observing the vector-boson-fusion production of a heavy neutral scalar decaying into a Z boson and the 125 GeV Higgs, demonstrating that the mere existence of this process confirms non-zero couplings necessary for CP violation.
