hep-th papers | Gist.Science

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.

Constraint on cosmological constant in generalized Skryme-teleparallel system

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 $f(T)$ 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.

Complex crystallographic reflection groups and Seiberg-Witten integrable systems: rank 1 case

This paper examines rank-one complex crystallographic reflection groups to establish their connection with Seiberg-Witten integrable systems for Minahan-Nemeshansky SCFTs of type $E_{6,7,8}$ , providing a compact geometric description of the associated elliptic fibrations and deriving their quantum spectral curves as Fuchsian ODEs.

The stringy geometry of integral cohomology in mirror symmetry

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.

Appearances are deceptive: Can graviton have a mass?

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.

Krylov complexity of thermal state in early universe

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.

Bound states of massive complex ghosts in superrenormalizable quantum gravity theories\

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.

Topological entanglement and number theory

This paper establishes a novel connection between topological entanglement and number theory by introducing a $q$ -deformed Witten zeta function within 3d Chern-Simons theory, demonstrating that the large- $k$ limit of Rényi entropies for torus link complements converges to values determined by classical Witten zeta functions, which admit a geometric interpretation via symplectic volumes of moduli spaces of flat connections.

Lorentzian homogeneous Ricci-flat metrics on almost abelian Lie groups

This paper studies Lorentzian left-invariant metrics on almost abelian Lie groups of dimension four or higher, constructing a geodesically complete, Ricci-flat, non-flat metric that generalizes the four-dimensional Petrov solution to arbitrary dimensions and admits closed timelike curves.

Gravitational waves in massive Horndeski theory with a potential

This paper investigates gravitational waves in linearized Horndeski theory with an arbitrary potential, demonstrating that the potential's minimum acts as an effective cosmological constant that induces distinct frequency and wave number redshifts while influencing the speed and polarization of scalar waves.

Free field realization of the Ding-Iohara algebra at general levels

This paper presents a unified free field realization of the Ding-Iohara algebra at arbitrary levels using six free boson fields, derived from a specialized factorization of the structure function, and subsequently develops intertwining operators based on this construction.
