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 rare exclusive decays of the Z boson into paired charmonium and bottomonium states using a relativistic quark model to construct decay amplitudes and calculate decay widths with and without relativistic corrections.
This paper derives a new, exact analytical upper bound on the CP-violating decay asymmetry for vanilla leptogenesis with two right-handed neutrinos, demonstrating that this bound is strictly lower than the standard Davidson-Ibarra bound (particularly for inverted neutrino mass hierarchies) and monotonically increases with the effective neutrino mass.
This paper extends the cosmological stasis framework to multiple recurrent epochs by deriving a closed-form gravitational-wave spectral template that uniquely identifies multi-stage stasis through characteristic amplitude steps and tilt accumulation, thereby providing a robust discriminator against constant-equation-of-state alternatives and establishing detectability criteria for such scenarios.
This paper critiques the standard formalism for calculating the isospin breaking correction in superallowed beta decays for violating nucleon basis independence and proposes a new perturbative "generating function approach" to achieve the precision required for testing Cabibbo unitarity.
This paper reviews how rapid advancements in quantum computing and sensing technologies are reshaping particle physics by enabling the study of nonperturbative dynamical processes and facilitating novel searches for physics beyond the Standard Model with unprecedented sensitivity.
This paper demonstrates that the computability of Generalized Parton Distributions (GPDs) in Lattice QCD can be extended to the critical regions by relaxing large momentum expansion conditions at high , thereby enabling the first lattice observation of the expected partonic threshold behavior and providing new predictions for GPDs in the distribution-amplitude-like region.
This paper presents the proceedings of the 2026 MDvDM conference, highlighting significant theoretical, computational, and experimental advancements in using natural and synthetic mineral crystals as detectors to measure nuclear recoils from neutrinos and dark matter over both laboratory and geological timescales.
This paper introduces a variational quantum-circuit model that leverages symmetry constraints and physics-inspired ansätze to provide a compact, high-accuracy, and unified representation of pion fragmentation functions across flavor channels and energy scales, demonstrating significant improvements in convergence and expressivity over traditional methods.
This paper demonstrates that for single-field slow-roll inflation with non-minimal coupling in Palatini gravity, the number of e-folds is independent of the coupling strength at leading order, enabling a universal mapping between the observables of the non-minimally coupled -attractor models and their minimally coupled counterparts, particularly showing how the strong coupling limit suppresses the tensor-to-scalar ratio and shifts the scalar spectral index.
This paper establishes an invertible map between 3D Breit-frame and 2D infinite-momentum-frame mechanical distributions for spin-1 hadrons by combining Abel transformations with recoil operators to demonstrate that, despite the added complexity of Wigner rotation-induced multipole structures, no new mechanical information is introduced beyond existing form factor constraints.
