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 exclusive electroproduction of quark and gluon dijets within the collinear factorization framework to probe generalized parton distributions, incorporating helicity contributions and elastic form factors while comparing predictions to HERA data and projecting future measurements for the Electron-Ion Collider.
This paper applies a Bayesian Markov Chain Monte Carlo approach to re-evaluate DUNE's long-baseline neutrino oscillation sensitivity using existing inputs, revealing enhanced octant sensitivity through post-hoc reactor constraints and presenting the first study of DUNE's sensitivity to the Jarlskog invariant.
This paper supports the interpretation of the as a -wave hadronic molecular state by demonstrating that its calculated strong decay widths, constrained by experimental branching ratios, agree well with observed data and predict a distinct signature in the unobserved channel.
This paper employs on-shell methods and complex factorisation constraints to derive the structure and couplings of massive supermultiplets, demonstrate that massless helicity-3/2 particles necessitate supergravity, and fully reconstruct the perturbative structure of gauged supergravity vacua via the super-Higgs mechanism.
The paper introduces **llm4smeft**, an open-source, locally runnable framework that combines a literature fine-tuned language model with retrieval-augmented generation to automate the selection of relevant SMEFT operators and their Fisher information for sparse global fits, thereby reducing reliance on manual theoretical insight.
This paper employs Born-Oppenheimer effective field theory to model quarkoniumlike states above open-flavor thresholds, revealing a spectrum organized by heavy-quark spin symmetry that includes both short-distance quarkonium resonances and long-distance molecular states, while providing multiplet assignments for experimental candidates and identifying the need for additional theoretical sectors to explain outliers.
Using finite-temperature and finite-density QCD sum rules, this study reveals that open-charm vector mesons ( and ) undergo substantial in-medium softening and significant reductions in their leptonic decay constants as baryon density increases, with the largest mass shifts reaching approximately and respectively, while finite density also lifts the vacuum degeneracy between particle and antiparticle states.
The paper analyzes the newly discovered gas-rich Cloud-9 as a Reionization Limited HI Cloud, demonstrating that while its observed properties are consistent with both standard cold dark matter and self-interacting dark matter models, the latter significantly reduces the statistical tension regarding the halo's unusually diffuse central density, thereby establishing RELHICs as a promising new probe for dark matter self-interactions.
This paper demonstrates that the large size of pion-like excitations in the stringy fluid regime of QCD above the chiral symmetry restoration temperature is a model-independent phenomenon required by current algebra, arising from Pauli blocking effects that cause these mesons to swell significantly.
Using a planar four-Fermi model within the large- approximation, this study demonstrates that a perpendicular magnetic field enhances the excitonic insulator condensate via magnetic catalysis, nonmonotonically shifts the critical chemical potential, alters the phase diagram's tricritical point, and induces characteristic changes in Hall conductivity that serve as signatures of excitonic ordering.
