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 investigates the strong and radiative decay widths of the state within a local hidden gauge molecular framework, finding that coupled-channel interactions and mixing significantly influence the strong decay width while anomalous terms prove negligible, ultimately calling for precise independent measurements to clarify the state's nature in light of recent Belle data.
This paper analyzes the reaction to explain the narrow width and the origin of "non-" peaks via triangle singularities, while demonstrating that the experimental technique of selecting mesons in a narrow mass window suppresses the observable strength of these singularities, suggesting they could be detected using alternative identification methods.
By working backwards from the requirements of vanilla two-flavor leptogenesis, this paper determines that the lightest right-handed neutrino mass scale in the Type I seesaw mechanism must lie between and GeV, while also identifying the corresponding general textures of the Dirac mass matrix.
This paper resolves the violation of local thermodynamic relations in relativistic spin fluids by identifying a specific family of pseudo-gauges that restore standard thermodynamics, thereby deriving universal relations and explicit equations of state for free Dirac fermions and scalar fields.
This paper proposes that a long-range parity-violating interaction mediated by the exchange of two neutrinos effectively acts as a contact term in atomic systems, producing a correction that resolves the existing discrepancy between the Standard Model prediction and experimental measurements of cesium parity violation while yielding weak mixing angle and weak charge values consistent with the Standard Model.
Using the functional renormalization group to systematically improve upon previous studies, this paper maps the QCD phase diagram at strangeness neutrality, predicting a critical end point at (92, 696) MeV and confirming consistency with both functional QCD and lattice QCD benchmarks.
This paper projects the sensitivity of paleo-detectors to various non-relativistic effective field theory dark matter-nucleus interactions, demonstrating that they offer superior or comparable discovery potential to current conventional direct detection experiments across a wide range of dark matter masses and interaction types.
The paper introduces , a process-independent software tool based on a fully-local nested soft-collinear subtraction scheme that calculates fully-differential cross sections for colour-singlet production in hadronic collisions up to next-to-next-to-leading order in QCD, with initial implementations for Higgs production via gluon fusion and Higgs-Strahlung.
This paper proposes a new nonet scheme for scalar mesons (, , , and ) as -wave quark-antiquark states while identifying as a glueball, supporting this classification through statistical and coalescence model calculations of their production yields in relativistic heavy ion collisions.
This paper investigates the electromagnetic structure of heavy quarkonia and the meson using a light-front quark model with variational wave functions, finding that the electromagnetic radii of and states are approximately 1.5 and 1.9 times larger than their counterparts, respectively, in agreement with lattice QCD data and other model predictions.
