Hep-Th, or high-energy theoretical physics, explores the fundamental building blocks of our universe and the forces that govern them. Researchers in this field use complex mathematics to understand everything from subatomic particles to the behavior of black holes, often pushing the boundaries of what we know about space and time.
At Gist.Science, we monitor the arXiv repository to ensure you stay ahead of the curve in this rapidly evolving discipline. For every new preprint uploaded to arXiv under this category, our team generates both accessible plain-language overviews and detailed technical summaries, making cutting-edge research understandable regardless of your background.
Below are the latest papers in high-energy theoretical physics, curated to help you navigate the most significant recent discoveries.
This paper reviews recent advancements in string theory model building for early and late-time cosmology, detailing a class of Kähler modulus-driven inflation models with axionic dark radiation production and presenting a string-theoretic axion hilltop quintessence model while analyzing the challenges of de Sitter vacua versus dynamical dark energy.
This paper computes the flux-induced F-term potential in 4d F-theory compactifications at large complex structure to identify two families of flux vacua with fixed complex structure fields, demonstrating that one family allows unbounded saxion vevs and a tadpole contribution that is a product of arbitrary integers, thereby challenging the Tadpole Conjecture.
This paper demonstrates that by constructing nested Rindler wedges displaced along a null direction, one can achieve selective thermalization of specific momentum modes for massless scalar fields and chiral excitations for massless fermions, offering new insights into quantum hair on horizons and potential chiral phenomena in the early universe.
This paper analyzes recent NOA and T2K data to test the non-unitary mixing hypothesis, providing updated best-fit parameters and tighter constraints on unitary violation while demonstrating that non-standard parameters can alleviate tensions between the experiments, alongside a projection of future sensitivities for NOA, T2K, and DUNE.
This paper presents a non-Lagrangian, non-perturbative derivation of anyonic topological order on magnetized M5-branes probing Seifert orbifolds by utilizing flux quantization within twisted equivariant Cohomotopy (Hypothesis H), thereby rigorously recovering abelian Chern-Simons theory and braid group actions essential for topological quantum computing.
This paper demonstrates that detecting tau neutrinos at the DUNE far detector significantly enhances sensitivity to Non-Standard Interactions, particularly the parameter, while also improving constraints on mass hierarchy, CP violation, mixing octants, and the unitarity of the PMNS matrix.
This paper proposes using diffusion models with transfer learning to generate neutrino mass matrices consistent with experimental data, revealing non-trivial distributions for CP phases and neutrino mass sums that offer new avenues for verifying lepton flavor models through future experiments.
This paper formulates a covariant Dirac oscillator in an non-Abelian gauge background, deriving matrix-valued spin-isospin couplings from the non-Abelian field-strength tensor while recovering the exactly solvable Moshinsky--Szczepaniak spectrum in the Abelian limit.
This paper presents a complete, chiral-phase-invariant Lagrangian describing axion interactions with pseudoscalar and (axial-)vector mesons within the three-flavor framework by incorporating the full Wess-Zumino-Witten term and instanton effects, which is then applied to compute decay widths for GeV-scale axions.
This paper investigates how a perfectly conducting plate modifies the Uehling potential in Quantum Electrodynamics by extending the method of images to the photon propagator, revealing that the plate's influence on this quantum correction is significantly stronger than naive classical expectations.
