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 study utilizes simulated High Luminosity LHC data to investigate the angular distribution of high-mass dimuon pairs in the Collins-Soper frame, employing a simplified Einstein-Cartan model to establish 95% confidence level upper limits on the masses of a spin-2 dark neutral gauge boson and the torsion field.
The paper introduces HDSense, a computationally efficient metric that ranks observable sensitivity by balancing information content and redundancy using one-dimensional histograms, enabling the identification of near-optimal parameter-constraining subsets for complex models like hadronization without requiring full likelihood calculations.
This paper generalizes the concept of family anomalies to broken generalized and categorical symmetries, utilizing anomaly inflow and SymTFTs to constrain the renormalization group flows and infrared phases of families of quantum field theories, with specific applications to 4d QCD-like theories deformed by multi-fermion interactions.
Motivated by recent near-threshold enhancements in top-quark pair production, this paper utilizes the instantaneous Bethe-Salpeter formalism to calculate the S-wave spectral structures of heavy-light systems containing a single top quark (, , and ), identifying them as quasi-bound configurations with masses slightly above the top-quark mass and offering qualitative insights into their potential production and decay patterns.
This paper demonstrates that while next-generation neutrino observatories like Jinping could theoretically detect the intense neutrino burst from a stellar helium flash out to nearly 3 parsecs, the absence of suitable nearby red giant candidates currently makes asteroseismology the only viable method for studying these events.
This paper investigates the discovery potential of doubly charged Higgs bosons at future colliders through three-body associated production channels, demonstrating that these processes can significantly exceed conventional pair-production rates and offer viable detection prospects for --$1500$~GeV with integrated luminosities in the few ab range.
This paper proposes that long-baseline atom interferometers like MAGIS and AION can serve as sensitive non-collider probes for supersymmetric hidden sectors by detecting coherent phase oscillations induced by ultralight moduli or hidden scalars, thereby mapping these signals to fundamental parameters of supersymmetric and string-motivated theories.
This paper demonstrates that a locally static Schwarzschild spacetime can be consistently embedded within a generalized cosmological time (GCT) background with an evolving lapse by satisfying Israel junction conditions, which yield a geometric consistency condition rather than new dynamics, thereby ensuring compatibility between local gravitational stability and non-standard cosmological time normalizations.
The paper demonstrates that existing radio telescopes like CHIME and FAST can effectively detect high-frequency gravitational waves from sources such as primordial black hole mergers and ultralight boson clouds by converting them into radio photons via the inverse Gertsenshtein effect, significantly outperforming many current experiments in this frequency regime.
This paper proposes that a neighboring brane-world could communicate with ours exclusively through gravity by utilizing the Kaluza-Klein tower as a multi-input multi-output channel, where information is encoded in the occupation patterns, phases, and arrival times of massive graviton modes above a specific energy threshold.
