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 introduces a differentiable, multi-scale Effective Field Theory framework that integrates renormalization-group evolution, matching, and experimental constraints to enable efficient gradient-based inference in large parameter spaces, as demonstrated through comprehensive 374-parameter SMEFT analyses.
This paper extends previous bounds on the axion-photon coupling by over an order of magnitude using the SACLA X-ray free electron laser and the Borrmann effect in Laue crystals, achieving the most stringent laboratory constraints to date for QCD axions in the 3.46–3.48 keV mass range.
This paper proposes that ultra-high-energy cosmic rays serve as a novel probe for memory-burdened primordial black holes, which could survive as dark matter by suppressing Hawking evaporation, and derives new constraints on their abundance by comparing theoretical proton and neutron emission models with observational data from the Pierre Auger Observatory.
This paper proposes a dark sector model where a spontaneous -breaking phase transition, potentially strengthened by an additional -odd scalar doublet to generate fermionic dark matter, produces a distinctive twin-peaked gravitational wave signal if the transition is first-order, or a single peak from domain wall annihilation if second-order.
This paper proposes a dedicated search strategy at the 14 TeV LHC utilizing initial-state radiation jets and soft leptons to probe the previously unexplored compressed mass spectrum of Type-II seesaw triplet scalars, demonstrating that discovery-level sensitivity can be achieved with 3000 fb⁻¹ of integrated luminosity.
This paper demonstrates that a dimensionless, scaled transverse-momentum spectrum exhibits universal behavior across heavy-ion collision conditions, serving as a powerful new probe that reveals collective dynamics and provides independent constraints on quark-gluon plasma properties through Bayesian analysis.
This paper investigates the in-medium properties of the meson with finite momentum in nuclear matter, revealing that while transverse polarization mass shifts remain momentum-independent, longitudinal shifts decrease quadratically with momentum due to specific vector mean-field and derivative interactions, offering new predictions for upcoming experiments at J-PARC.
This paper employs light-cone sum rules with both right-handed and left-handed chiral currents to calculate transition form factors, yielding branching fractions and CKM matrix element values that show good agreement with existing literature.
This paper proposes a framework combining lattice QCD inputs with first-order symmetry breaking to predict specific branching ratio measurements for semileptonic decays that can definitively determine whether the observed large symmetry breaking stems from unexpected hadronic mechanisms or new physics.
This paper demonstrates that universal quartic modifications to relativistic dispersion relations emerge generically from deformation-quantized phase spaces under minimal kinematical assumptions, a result confirmed through three independent mathematical frameworks: Fedosov-Berezov quantization, spectral geometry, and topos theory.
