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.

The paper advocates for a bold, long-term shift in particle physics research toward the development of a yotta-eV scale tau-lepton collider located in the Oort cloud, arguing that despite requiring Kardashev Level-I or II civilization capabilities, this approach should become the community's primary focus for precision Higgs studies and new particle discovery.
Using the parity doublet model, this paper demonstrates that gravitational waves from the nuclear liquid-gas phase transition in QCD could produce detectable signals in the millihertz to nanohertz bands, whereas those from the chiral phase transition are too weak to be observed, thereby linking the chiral invariant mass to potential gravitational wave signatures of nucleon mass origins.
This paper utilizes the Herwig 7 framework to demonstrate that massive bosons produced via BSM parton shower radiation, rather than direct hard processes, populate non-isolated regions within jets, offering a novel and previously overlooked avenue for discovering new physics through jet substructure analysis at the LHC and future colliders.
This paper investigates the photoproduction and nuclear absorption of charmonium on C and W targets near the kinematic threshold using a collision model with nuclear spectral functions, demonstrating that calculated observables are sensitive to absorption scenarios and could help determine the -nucleus cross section for future experiments at the CEBAF facility.
This paper establishes an analytical connection between triaxial nuclear shapes and three-particle correlations in relativistic heavy-ion collisions, demonstrating that specific flow and momentum fluctuation observables are directly proportional to the nuclear triaxiality parameter .
This paper presents the first relativistic next-to-leading order Chiral Perturbation Theory calculation of non-leptonic hyperon decays, explicitly incorporating loop corrections and resonance saturation for low-energy constants to achieve a successful fit of both - and -wave amplitudes while highlighting the crucial role of resonances.
This paper demonstrates that baryogenesis via sphalerogenesis can be successfully realized in Standard Model extensions featuring new multiplet fields (such as fermionic quintuplets and septuplets) with TeV-scale masses and CP-violating Yukawa interactions, yielding a phenomenologically viable and testable scenario consistent with current electron electric dipole moment limits and future collider searches.
This paper investigates charged current induced electron-proton scattering at JLab and MAMI by calculating various cross sections and polarization observables with and without time-reversal invariance, aiming to provide alternative constraints on the axial vector form factor to benefit neutrino oscillation experiments.
This paper presents a sensitivity study using the BESIII experiment to propose a model-independent method for determining the branching fraction of decays into three-body final states by simultaneously analyzing four specific semileptonic -meson decay channels.
This paper demonstrates that combining next-to-next-to-leading-order Standard Model predictions with approximate next-to-next-to-leading-order SMEFT interference corrections for top-antitop pair production at 13 and 13.6 TeV yields robust, high-precision constraints on the top chromomagnetic operator , probing effective scales up to 3.9 TeV.
