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.

Quantum Airy Structures and Matrix Models: a supercurrent approach

This paper develops a unified super-current formulation of N=1\mathcal{N}=1 super-Virasoro constraints for external-source models across all sectors, establishing an exact similarity transformation between NS-NS and R-R differential constraints to propose a concrete candidate system of Ward identities for a supersymmetric extension of the Kontsevich matrix model.

Spinning Black Hole Scattering at O(G3S2)\mathcal{O}(G^3 S^2): Casimir Terms, Radial Action and Hidden Symmetry

This paper resolves ambiguities in post-Minkowskian binary dynamics by determining spin Casimir terms from massive scattering amplitudes, thereby completing the O(G3S2)\mathcal{O}(G^3 S^2) calculation for spinning black hole scattering, establishing a generalized amplitude-action relation, and revealing a hidden spin-shift symmetry linked to the integrability of Kerr orbits.

On the total derivative divergence for a nonminimal vector operator

This paper utilizes Riemann's normal coordinates to confirm previous calculations of the R\Box R term in the vacuum effective action divergence for a nonminimal vector field, revealing that this local term is gauge-fixing dependent in the electromagnetic case—a finding that contradicts general quantum correction theorems and raises questions regarding gauge-dependent infrared regulators.

Particle Creation in a Cosmological Background in Analogy to the Schwinger Effect

This paper rigorously derives particle production in a cosmological FLRW background by modeling a long gravitational pulse analogous to the Schwinger effect, utilizing Heun equation connecting formulas to demonstrate that the resulting particle spectrum exhibits a Planckian distribution with a temperature inversely proportional to the duration of the scale change.

Revisiting the Quantum Geometry of Torus-fibered Calabi-Yau Threefolds

This paper establishes that the modularity of topological string amplitudes on torus-fibered Calabi-Yau threefolds arises from the wave-function property of the partition function under relative conifold monodromy, thereby linking genus-zero Gopakumar-Vafa invariants to D4-D2-D0 Donaldson-Thomas indices and providing a holomorphic, modular-covariant formulation verified across numerous del Pezzo-fibered examples.

Non-Thermal Leptogenesis in the BLSM with Inverse Seesaw Mechanism

This paper demonstrates that non-thermal leptogenesis, driven by the decay of a heavy BLB-L Higgs boson, can successfully generate the observed baryon asymmetry in a gauged U(1)BLU(1)_{B-L} extension of the Standard Model with an inverse seesaw mechanism, overcoming the strong washout effects of O(1)\mathcal{O}(1) Yukawa couplings through a specific scalar mass tuning that allows for a reduced reheating temperature.
