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 significant CP violation induced by forward-backward asymmetry in the decay within the phase space dominated by and resonances, predicting asymmetries of up to 35% that are potentially observable by Belle and Belle-II collaborations.
This paper presents the first calculation of second-order corrections for pseudo-scalar Higgs boson decay into three partons ( and ) expanded to higher orders in the dimensional regulator within an effective theory framework, providing finite amplitude pieces essential for predicting NNLO differential distributions and future three-loop cross sections at hadron colliders.
This paper demonstrates that Affleck-Dine baryogenesis can be realized with low-energy, non-supersymmetric physics involving a light scalar field, which produces detectable gravitational waves in the LIGO frequency range, thereby establishing a new complementarity between gravitational wave astronomy and particle physics experiments.
This paper critiques previous claims of Leggett-Garg inequality violations in neutrino oscillations by identifying unsuitable macrorealistic modeling in statistical tests and proposes an improved methodology that yields revised, more modest evidence for such violations at the 2–3σ level using MINOS data.
This paper revisits the quantization of gauge field theories by proposing a "sandwich quantization scheme" where constraints are imposed as vanishing matrix elements between physical states, revealing new solutions and offering fresh insights into the physical Hilbert space of gauged systems.
This paper presents NNLO+NNLL threshold resummation results for on-shell -boson pair production at the LHC, demonstrating that the resummation enhances the cross-section by approximately 6.3% at high invariant masses while significantly reducing scale uncertainties from 6.8% to 4.1%.
This paper demonstrates that two distinct frameworks for perfect spin hydrodynamics—based on classical kinetic theory and the Wigner function—yield conserved currents with identical forms at every order of spin polarization expansion, differing only by a monotonically increasing multiplicative factor.
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.
