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 employs nonlinear sequence-transformation techniques, specifically the Shanks transformation and Wynn's -algorithm, to estimate higher-order perturbative coefficients and predict the QCD correction for hadronic decays, offering an efficient alternative to explicit multi-loop calculations.
This work investigates the tensor form factors and quark tensor charges of the hyperons , , and within the framework of QCD sum rules and provides new non-perturbative insights into the spin structure of spin-3/2 baryons for future phenomenological and experimental studies.
This paper proposes the reaction as a viable method for the LHCb collaboration to observe a predicted state with a narrow width of approximately 200 keV, thereby shedding light on the role of coupled channels in the structure of hidden-charm pentaquarks.
This paper investigates the classical stability of metastable strings arising from an symmetry breaking chain, identifying parameter regions where such instabilities significantly impact the viability of these strings as candidates for the gravitational wave background detected by Pulsar Timing Arrays.
This paper demonstrates that ultrarelativistically frozen-out (UFO) dark matter candidates, particularly those mediated by a portal, represent a viable and detectable alternative to traditional WIMPs, with current experiments like LZ and XENONnT already constraining their parameter space and future detectors such as SuperCDMS SNOLAB poised to explore significant regions in the 0.5–10 GeV mass range.
This paper summarizes the current status of exclusive semileptonic branching fractions, identifies unmeasured components dominated by baryonic and final states, and proposes specific candidates and simplified models to close the gap with inclusive measurements.
This paper demonstrates that multi-gluon and multi-graviton radiation in strong field shockwave scattering can be modeled as generalized Susskind-Glogower squeezed coherent states via the QCD-Gravity double copy, revealing that large squeezing parameters in nearly minimal uncertainty configurations could produce gravitational wave quantum noise exceeding the sensitivity of current and future detectors.
This paper presents a solution to the boundary problem for the axial-vector field in the hard-wall AdS/QCD model by deriving fundamental solutions to a homogeneous ordinary differential equation and employing an iterative method to establish sufficient conditions for the Fredholm solvability of the resulting integral equation.
This study reports the first identification of the Einstein-de Haas effect in QCD matter, demonstrating that magnetic-field-induced spin alignment alone can generate collective rotation comparable to fluid vorticity in heavy-ion collisions, thereby establishing hot QCD matter as a self-vortical magnetofluid.
This paper employs a symmetry-preserving contact interaction within the Schwinger-Dyson and Bethe-Salpeter framework to calculate the elastic form factors, charge radii, magnetic moments, and quadrupole moments of various axial-vector mesons, revealing that their electric form factors cross zero at lower values than vector mesons and that including an anomalous magnetic moment term significantly impacts their magnetic and quadrupole properties.
