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 derives explicit expressions for parton helicities at arbitrary kinematics within the double-logarithmic approximation, advocates for -factorization over collinear factorization when accounting for orbital angular momentum, and demonstrates that DGLAP asymptotics are less singular at small than Regge asymptotics.
This paper applies the quantum bootstrap method to non-relativistic potential models, successfully validating the approach against charmonium and bottomonium data and predicting a quasi-bound toponium state with a mass of approximately 344.3 GeV that aligns with recent ATLAS and CMS observations.
This paper presents the first implementation and validation of the Martini-Ericson-Chanfray-Marteau RPA-based model for quasielastic and multinucleon neutrino and antineutrino interactions within the GENIE event generator, demonstrating reasonable agreement with experimental data from T2K and MicroBooNE.
This paper investigates the branching ratios of the rare decay for three CP-even Higgs bosons within the broken-phase Next-to-Two-Higgs-Doublet Model (N2HDM), incorporating one-loop corrections to identify viable parameter regions that explain the ATLAS signal strength enhancement and demonstrate the utility of dimuon precision measurements in probing extended Higgs sectors.
This paper investigates the LHC collider signatures of neutral scalar cascades in the -symmetric Three Higgs Doublet Model, demonstrating that while the Medial Hierarchy scenario allows for discovery-level sensitivity of CP-even and CP-odd scalars via the process, the Regular Hierarchy scenario requires substantially higher luminosity to achieve similar detection prospects.
This paper establishes a universal theoretical framework for quantifying quantum entanglement in the decay angular distributions of arbitrary spin particle-antiparticle pairs, deriving explicit observables and proportionality factors that reveal bosonic decays offer model-independent tests while fermionic cases require supplementary polarization information.
This paper proposes a two-loop rainbow neutrino mass model based on a gauged subgroup of a non-invertible symmetry, which simultaneously explains neutrino oscillations, provides a stable vector-like fermion dark matter candidate, and predicts a sum of neutrino masses in the normal hierarchy that exceeds that of the inverted hierarchy.
This paper investigates how decay channels influence near-threshold mass scaling using potential models, demonstrating that the pole of a quasibound state below the threshold is not continuously connected to that of a resonance state above the threshold, while clarifying the correspondence between single-channel complex and coupled-channel real potential approaches.
This study employs a transport approach to demonstrate that photon-tagged jets effectively mitigate selection bias, thereby revealing medium-induced angular broadening in PbPb collisions that contrasts with the narrowing observed in inclusive jets.
This paper employs a bottom-up approach to analyze one and two texture zeros in the neutrino mass matrix using current oscillation data, identifying specific allowed vanishing elements for normal and inverted mass orderings while establishing correlations between the lowest neutrino mass and CP-violating phases.
