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 proposes a gauge-theoretic framework for plasticity derived from spontaneous spacetime symmetry breaking, demonstrating that defect kinematics are fundamentally determined by non-dissipative symmetry principles and conservation laws, with dissipative flow emerging as a controlled deformation of this conservative structure.
This paper proposes and evaluates three anomalous holographic hard wall models with logarithmic and power-law corrections to baryonic operator dimensions, demonstrating that these modifications significantly improve the description of light baryon spectra and yield approximately linear Regge trajectories compared to the original hard wall model.
This paper adapts cluster-algebraic methods from super Yang-Mills theory to derive candidate alphabets for 5- and 6-point QCD processes, successfully recovering known 1-loop and massless 2-loop results while predicting new letters, including nested square roots for massive 6-point kinematics.
This paper demonstrates that within generalized teleparallel gravity, a matter-bounce cosmological scenario naturally explains the current lack of observational evidence for the Kalb-Ramond field by confining its energy density to the bounce epoch, thereby favoring this model over a symmetric bounce.
This paper extends the Einstein-Skyrme system to teleparallel gravity frameworks, demonstrating that while the TEGR model aligns with previous results for a positive cosmological constant, the generalized gravity scenario imposes specific upper and lower bounds on the cosmological constant that depend on the model's nonlinearity parameter, thereby constraining the existence of black-hole solutions with fractional baryon numbers.
This paper examines rank-one complex crystallographic reflection groups to establish their connection with Seiberg-Witten integrable systems for Minahan-Nemeshansky SCFTs of type , providing a compact geometric description of the associated elliptic fibrations and deriving their quantum spectral curves as Fuchsian ODEs.
This paper investigates the physical significance of torsion co-cycles in the cohomology of projective Calabi-Yau three-folds within (2,2) superconformal field theories, revealing that one torsion subgroup relates to orbifold constructions while the other encodes topologically non-trivial flat gerbes for the NS-NS B-field, thereby refining mirror symmetry and generalizing duality to treat the topology of flat gerbes on equal footing with the manifold's topology.
This paper demonstrates that while linear gravitational perturbations on cosmological backgrounds of massive fermionic fields appear to acquire an off-shell mass in the action, this mass vanishes at the level of the equations of motion, ensuring that gravitons remain massless on-shell even when the background is driven by one-loop fermion backreaction.
This paper employs a purification scheme to analyze the Krylov complexity of thermal states across the early universe's inflationary, radiation-dominated, and matter-dominated eras, revealing an exponential growth of complexity and strong dissipation during inflation that transitions to saturation and weak dissipation in later epochs due to particle production.
This paper demonstrates that superrenormalizable quantum gravity theories with complex ghost masses, despite failing standard consistency criteria like the Källén-Lehmann representation, can confine unphysical massive excitations into normal composite bound states, a mechanism with significant cosmological implications.
