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 thesis investigates the influence of radiative corrections on modeling electroweak processes at future lepton colliders, aiming to enhance the precision of Standard Model tests from the Z pole to multi-TeV energies to address unresolved cosmological questions.
Using updated 2026 quark-mixing data and NuFIT 6.1 oscillation likelihoods, this study revisits quark-lepton complementarity to demonstrate that while the specific 2016 atmospheric-angle prediction is disfavored, the broader quark-lepton correlation structure remains robust and persistent, with approximately 72% of the ensemble favoring a tribimaximal over a bimaximal texture.
This paper computes quark and meson spectral functions in low-energy two-flavour QCD by employing the spectral functional renormalisation group in Minkowski space to incorporate all-order pion and scalar -mode scatterings and decays through a self-consistent treatment of scattering tails and momentum-dependent resummation of the four-meson vertex.
This paper demonstrates that the rigorous results for triangle Feynman diagrams in the timelike region, typically derived via dispersion representations, can be directly reproduced using the Feynman-parameter integral representation by simply applying the standard prescriptions to the external momenta and internal masses.
This paper derives comprehensive constraints and future sensitivity projections for photon-mediated interactions of ultraheavy dark matter (up to GeV) across multiple direct detection experiments, with a specific focus on establishing new sensitivity ceilings for millicharged dark matter that close significant gaps between existing direct detection and neutrino experiment limits.
This paper demonstrates that pion-catalyzed reactions, rather than nucleon coalescence or statistical hadronization, are the dominant mechanism for light (anti-)nuclei production in high-energy collisions, as evidenced by a relativistic kinetic model that successfully reproduces experimental pion-nucleus femtoscopic correlation data while other models fail.
This paper derives Standard Model predictions for CP asymmetries in singly-Cabibbo suppressed decays using approximate symmetry with first-order breaking effects, establishing correlations between specific decay modes to guide future experimental tests and the extraction of key theoretical parameters.
The paper demonstrates that the upcoming Moon-orbiting Hongmeng satellite experiment can significantly tighten current constraints on the dark matter-baryon scattering cross-section by a factor of 39 over a five-year mission, or by a factor of 4 within just one month, by leveraging its ability to measure the global 21cm signal in the redshift range of 11–46 while minimizing terrestrial interference.
This paper investigates the rare decay within both the Standard Model and scalar leptoquark scenarios, providing theoretical predictions for key observables to guide future experimental searches for new physics at Belle II and LHCb.
This paper proposes a mass-varying sterile neutrino dark matter model, where coupling active and sterile neutrinos to a scalar field generates the observed relic density while simultaneously resolving the Hubble tension, with its parameter space fully testable by future X-ray missions.
