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.

Using lattice QCD simulations with improved actions, the study demonstrates that localized low-lying Dirac eigenmodes emerge at a temperature of 150–160 MeV, placing the onset of this localization phenomenon firmly within the chiral crossover region.
This paper proposes that rotating synchrotron radiation (RoSyRa) from a magnetized, rotating quark-gluon plasma generates a low-transverse-momentum photon spectrum with significant elliptic flow, offering a viable solution to the "direct photon puzzle."
Using QCD sum rules and the iterative dispersion relation method, this study investigates the and dibaryons, finding that the scalar states are lighter than their tensor counterparts and that while the bottom system may form bound states in the scheme, both systems are predicted to be much heavier in the on-shell scheme.
This paper proposes using ultra-peripheral Au+Au collision data from the PHENIX experiment at RHIC to search for GeV-scale axion-like particles via the resonant process, demonstrating sensitivity to previously unexplored mass and coupling regions.
This paper evaluates the impact of cascade production on long-lived particle detection at the SHiP experiment, finding that while such processes can enhance event rates for light axion-like particles, the resulting soft kinematics and daughter-level acceptance constraints generally suppress the observable signal for both axion-like particles and heavy neutral leptons, rendering the cascade contribution subdominant except in specific low-mass scenarios.
This paper utilizes the perturbative QCD approach and flavor symmetry to calculate sizable branching ratios (on the order of ) for semi-invisible meson decays into light baryons and dark baryons, suggesting these processes as promising channels for dark matter searches at hadron colliders and B factories.
The paper introduces the Maximal Abelian Flavor Symmetries (MAFS) framework, which explains quark and lepton mass hierarchies and mixing angles using a minimal set of small parameters without arbitrary fermion charges, successfully describing flavor patterns in and unified theories while linking them to observed baryon asymmetry.
This paper utilizes a Regge framework applied to high-energy polarized photoproduction data from GlueX to achieve the first complete determination of the vector and tensor couplings between the system and the , , and mesons.
This paper presents a unified three-flavor analysis demonstrating that Earth's density stratification and Planck-scale quantum-gravity corrections act as correlated systematic uncertainties in long-baseline neutrino oscillations, where their interplay can significantly bias or even reverse the inferred CP-violating phase, particularly at baselines exceeding 5000 km.
This paper proposes a new mechanism for the annihilation of cosmologically problematic domain walls attached to cosmic strings in global symmetry models, demonstrating that radiative corrections from small bare fermion masses can generate a temperature-dependent bias that triggers the network's decay, using a majoron framework with right-handed neutrinos as a representative example.
