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 initiates a precision study of boosted jet substructure using energy correlators applied to hadronic Higgs decays, demonstrating that the two-body decay manifests as a distinct angular peak and that infrared scales like the dead-cone effect and confinement transition are resolvable, thereby enabling precision electroweak studies and new physics searches.
Using a 12.5-year IceCube high-energy starting events dataset, this study finds no significant correlation between tidal disruption events and high-energy neutrinos, thereby placing stringent constraints on the fraction of jetted TDEs and their associated cosmic ray energies.
This paper proposes a method to detect a CP-violating electromagnetic vacuum angle using Event Horizon Telescope observations of Sgr A* and M87* by analyzing time-averaged polarization residuals and universal topological signals that distinguish the predicted Fischler-Kundu Hall current from confounding plasma effects, though it concludes that current data is insufficient for such a test.
This paper offers a pedagogical introduction to the Silver Blaze problem in QCD, which addresses the paradox of why physical observables remain unchanged below a critical chemical potential despite the chemical potential altering the Dirac operator's eigenvalues, by analyzing the behavior of functional integrals and the role of phase cancellations in gauge configurations.
This paper utilizes Bayesian thermal analysis of hadron yields from STAR Ru+Ru and Zr+Zr isobar collisions to precisely extract chemical potential differentials in the QCD phase diagram, thereby validating these collisions as a high-precision probe for four-dimensional QCD thermodynamics against lattice-QCD and Chiral Mean Field model predictions.
This paper presents the expected precision for measuring the Higgs boson production cross-section times branching ratio in the fully leptonic decay mode at the FCC-ee, predicting relative uncertainties of 2.9% at 240 GeV and 6.8% at 365 GeV for the specified luminosity scenarios.
This paper develops a systematic Regge-theory framework for high-energy gravitational scattering of massive particles with multiple graviton emissions, unifying quantum and classical descriptions through exponential S-matrix and shock-wave formalisms to compute specific amplitudes and waveforms for ultra-relativistic Kerr black holes.
This paper outlines the LUXE experiment's use of high-intensity laser and electron beam collisions to probe non-perturbative strong-field QED phenomena like vacuum pair production, while also exploring how future colliders and beam-dump experiments can extend these studies to higher energy scales and search for new physics.
This paper constructs a quantum Schwinger-Keldysh effective field theory for diffusive hydrodynamics that enforces fluctuation-dissipation relations via KMS symmetry to reveal intrinsically non-Gaussian noise, ultimately deriving quantum corrections to density-density correlation functions that generalize hydrodynamic long-time tails to all orders in .
This paper employs a neural-network-based solution to nonlinear integral equations derived from unitarity and crossing symmetry to construct a solvable family of nonperturbative 4D scattering amplitudes that exhibit rich features like particle production and Regge behavior, while demonstrating that multi-particle data can be dynamically tuned to suppress low-spin production through a phenomenon termed "Aks screening."
