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.

Using an effective Lagrangian approach calibrated to existing data, this study successfully reproduces the production cross sections of high-spin and mesons in reactions and predicts measurable, forward-peaked production rates for their partners, suggesting their feasibility for observation in future meson-beam experiments.
This paper presents the public release of OpenGadget3, a cosmological hydrodynamical N-body code featuring a robust implementation of self-interacting dark matter that supports various elastic scattering cross-sections and two-species models, validated through accuracy tests and performance scaling.
This paper investigates the production of global vortex-antivortex pairs in 2+1 dimensions through numerical scattering experiments where a complex scalar field and a real scalar scatterer interact solely via a quantum mediator, revealing that vortex creation is highly sensitive to initial conditions and exhibits a chaotic parameter space with isolated production regions.
Using the functional renormalization group within the quark-meson model, this study demonstrates that the critical scaling region of the chiral phase transition systematically shrinks as chemical potential increases, with consistent results observed across both local potential approximations.
This paper demonstrates that helicity amplitudes for vector-boson decays to massless leptons, despite appearing to project only onto transverse polarization, encode complete information about all polarization states (including longitudinal) through little-group covariance, allowing the full covariant matrix to be reconstructed from any single polarization component using simple replacement rules in the massive spinor-helicity formalism.
This paper investigates the global spin polarization of hyperons in heavy-ion collisions by incorporating quark spin correlation effects, utilizing experimental data to derive constraints and inequalities that could reveal evidence of such correlations at lower collision energies.
This paper investigates fragmentation contributions to transverse nucleon spin observables in semi-inclusive deep-inelastic scattering at next-to-leading order within the collinear twist-3 factorization framework, confirming the validity of the formalism at the one-loop level and providing numerical predictions for HERMES and future EIC kinematics.
This paper employs QCD sum rules within a diquark model to systematically calculate the mass spectrum of hidden-charm singly-strange pentaquark states () with quantum numbers , , and , proposing specific and decay channels for their experimental detection in the mass spectrum.
This paper demonstrates that within the most general formulation of gravity with independent metric and connection, a unique naturally light vector or scalar distortion field emerges as a dynamical degree of freedom, notably predicting a light scalar particle that mixes with the Higgs boson.
This paper demonstrates that gluon Bose enhancement in the nuclear wave function significantly increases the cross section for incoherent diffractive dijet production when the jets have equal and aligned transverse momenta, an effect that persists and is amplified by JIMWLK evolution in both dilute and dense regimes.
