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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper presents a novel, systematic method for symbolically reducing multi-loop Feynman integrals to master integrals by leveraging generating functions to derive efficient recurrence relations that circumvent the exponential complexity of traditional integration-by-parts techniques.
This paper presents the first complete calculation of the remaining formally NLO multi-parton contributions to the inclusive radiative decay , providing fully analytic results in terms of multiple polylogarithms and demonstrating that their numerical impact on the decay rate is small due to a partial cancellation with leading-order terms.
This paper investigates linearly stable black hole solutions in nonlinear electrodynamics coupled with Horndeski vector-tensor theory, finding that while nonsingular black holes are inherently unstable due to Laplacian instabilities, singular black holes can satisfy stability conditions only if the Horndeski coupling is sufficiently weak, as strong coupling generally induces instabilities in the high-curvature regime.
This paper presents the first evaluation of virtual resonance contributions to charged-current (anti)neutrino-nucleon elastic scattering at GeV energies, demonstrating that these intermediate states induce permille-level corrections to the cross sections while exhibiting expected infrared behavior.
This paper proposes a GUT-scale Higgs inflation model driven by MSSM superfields with a specific superpotential and fractional shift-symmetric Kähler potentials, demonstrating that its parameters yield inflationary observables consistent with ACT DR6 data while simultaneously addressing the MSSM -problem and enabling baryogenesis.
This study investigates thermal photon production in a 1+1D quark-gluon plasma under strong magnetic fields using a magnetohydrodynamic framework with Bjorken flow, revealing how the magnetic field decay rate and initial strength significantly influence temperature evolution and photon yields across different transverse momentum ranges.
This paper derives non-relativistic atomic potentials and identifies specific observables, such as energy shifts and various multipole moments, that are sensitive to couplings with hypothetical cosmic fields from light bosons predicted by extensions to the Standard Model.
By comparing comprehensive hadronic interaction models with sudden-conversion models against ALICE data, this study demonstrates that pion-kaon emission asymmetries and femtoscopic radii scale with particle multiplicity and require the inclusion of hadronic-stage interactions to be accurately described.
This paper proposes that ultralight dark matter can be detected at colliders not as a standard isolated resonance, but as a "smeared" oscillating resonance caused by a mediator whose mass varies over time, offering a unique discovery channel that complements existing constraints from atomic clocks.
This paper demonstrates that within the Lorentz covariant relativistic generalized uncertainty principle framework, the canonical and Belinfante-Rosenfeld angular momentum tensors for gauge fields satisfy standard conservation laws despite Planck-scale minimal length effects, which introduce higher-order corrections to angular momentum density and the Poynting vector while recovering Maxwell's theory in the limit of vanishing RGUP parameters.
