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 the appropriate initial conditions for hydrodynamic evolution in small collision systems can be derived by coarse-graining the proton's quantum wave function into a semi-classical, positive-definite Wehrl-like entropy, thereby bridging the gap between pure quantum states and the maximally mixed states required by relativistic hydrodynamics.
This paper extends the 331LHN model by introducing scalar leptoquarks to demonstrate that a singlet leptoquark with a mass between 1.8 and 6 TeV can explain the muon anomalous magnetic moment discrepancy while satisfying constraints from lepton flavor violation and LHC bounds, with a predicted normal hierarchical Yukawa coupling pattern and suppressed current collider signals.
This paper systematically analyzes ultralight dark matter effects on neutrino oscillations using T2K and NOA data, revealing that stochastic fluctuations in the low-mass regime significantly relax coupling constraints while failing to resolve the existing tension in the CP-violating phase between the two experiments.
The paper demonstrates that the standard low-energy effective field theory of quantum gravity predicts unobservably small vacuum fluctuations in interferometers, implying that any future detection of large gravitationally-induced length variations would signal a fundamental breakdown of this theory.
This paper derives gravitational positivity bounds for the Higgs-portal scalar dark matter model, revealing that new physics must emerge below GeV for light dark matter without self-coupling, while heavy dark matter (– GeV) with specific couplings can satisfy grand unified theory scale constraints and be consistent with the observed relic abundance via the freeze-in mechanism.
This paper investigates normal mode analysis in relativistic massive transport by demonstrating how particle mass induces coupling between sound and heat channels, alters the branch cut structure responsible for Landau damping, and leads to non-monotonic dependencies in the critical wavenumbers for collective modes.
This paper introduces a computationally efficient Bayesian framework for Parton Distribution Function (PDF) determination that utilizes low-dimensional linear models derived from neural network bases to provide robust uncertainty estimates and transparent control over model selection, as validated through synthetic data and closure tests.
This paper demonstrates that chiral-odd dimeson generalized distribution amplitudes, which encode the spin-orbit correlation in spin-zero mesons, can be experimentally accessed in reactions through the interference between leading one-photon and two-photon exchange amplitudes, offering a direct path to probe this previously unmeasured sector of meson structure at facilities like BES III.
This paper refines the theory of axion double level crossings in multi-axion systems, demonstrating that these phenomena—characterized by a high-temperature crossing followed by a QCD-induced crossing—are common in axion models but are constrained by the number of axions () in both light and heavy scenarios, with significant implications for axion cosmology.
This paper proposes using linear Paul traps with single or multi-ion configurations to detect megahertz gravitational waves via graviton-photon conversion or relative-motion excitations, demonstrating that entangling vibrational qubits enhances signal probability by a factor of to surpass the standard quantum limit.
