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 a mechanism within effective field theory where higher-order Higgs couplings violate the conventional Goldstone Equivalence Theorem expectations, selectively amplifying Higgs-rich final states (such as multi-Higgs, $ht$, and ) to become the dominant discovery channels for heavy resonances beyond the Standard Model.
This paper demonstrates that Many-Body Gravity (MBG), a modified 5-D gravity theory, naturally reproduces cosmic inflation and resolves time-definition issues in non-interacting universes by utilizing entropic terms and interacting massless scalar fields, all without requiring dark matter.
This paper proposes an efficient framework for analyzing quantum field theories by combining a Daubechies wavelet basis with Similarity Renormalization Group flow equations to systematically decouple degrees of freedom across scales, thereby enabling the extraction of low-energy spectra from reduced-resolution Hamiltonian blocks with significantly lower computational cost.
This paper demonstrates that for inflationary models with monomial potentials (), the inflaton's asymptotically vanishing mass allows it to be regenerated from the thermal plasma long after reheating, offering a new framework to constrain reheating mechanisms and potentially explain dark matter.
This paper investigates non-equilibrium effects in a two-scalar sequential freeze-in dark matter model, demonstrating that full phase-space treatments can yield relic abundance predictions deviating by up to an order of magnitude from traditional number-density approaches, thereby underscoring the necessity of advanced numerical tools for accurate multi-component dark sector modeling.
This paper summarizes recent BESIII results on charmed-baryon decays derived from the world's largest sample of pairs, highlighting the observation of the rare semi-leptonic decay , the first measurement of the decay asymmetry in , and various branching fraction measurements and partial wave analyses.
This paper reviews recent progress in the hadronic light-by-light contribution to the muon and presents new holographic QCD predictions, particularly regarding tensor-meson contributions, which offer a potential resolution to the tension between lattice and data-driven results by yielding a sizable positive contribution consistent with short-distance constraints.
This paper investigates the parameter space for a vanishing effective Majorana mass in a sterile neutrino framework, demonstrating that while cosmological bounds on the sum of neutrino masses constrain the sterile mixing angle and lightest active neutrino mass, the resulting cancellation mechanism renders the sterile mixing angle insensitive to the high-precision solar oscillation measurements expected from the JUNO experiment.
This paper analyzes 7 TeV LHCb Collaboration data on two- and three-pion Bose-Einstein correlations by combining the Glauber-Lachs formula with a two-component pion production model, utilizing specific pion exchange functions extended into four-dimensional Euclidean configuration space.
This paper analyzes the production of doubly heavy quarkonia ( and charmonia) via the top-quark decay channel within the NRQCD framework, revealing significant decay widths that could yield thousands of events annually at the LHC and offering a sensitive probe for validating the narrow-width approximation.
