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.

Safety of dynamical SUSY breaking and gaugino condensation in models of spontaneous CP violation

This paper investigates the safety of spontaneous CP violation in supersymmetric models by demonstrating that while certain dynamical SUSY breaking and gaugino condensation scenarios preserve CP, others can generate dangerous complex phases in the superpotential constant or F-term, thereby reintroducing the strong CP problem through both anomaly mediation and vacuum misalignment with messenger fields.

Segre determinants and MHV gravity amplitudes

This paper presents a Segre-Veronese construction that generates polynomial solutions for tree-level MHV gravity amplitudes, demonstrating that while the five- and six-point cases align with Hodges' formula, solutions for $n \geq 7$ yield new, linearly independent elements distinct from the Hodges numerator.

Conformal Anomalies and Generalised Energy Conservation in De Sitter Spacetime

This paper demonstrates that the Generalised Energy Conservation condition for de Sitter scattering amplitudes with integer conformal dimensions is equivalent to the absence of boundary conformal anomalies, revealing that such solutions constitute a measure-zero subset of holographically consistent interactions and providing novel constraints relevant for testing the stability of non-supersymmetric AdS $_4$ vacua.

Projected Yang-Mills Theory and the MacDowell-Mansouri Analogy

This paper demonstrates that a specific constrained $SO(2n)$ gauge theory with a degenerate curvature kinetic operator and an adjoint Higgs field restricted to the $SO(2n)/U(n)$ orbit is locally equivalent to $SU(n)$ Yang-Mills theory, while also drawing structural parallels to the Stelle-West Higgs-gravity action and introducing projected Pontryagin theories.

Reheating surface volume renormalization and eternal inflation under broken scale invariance

This paper demonstrates that the slight breaking of scale invariance, characterized by a negative spectral index deviation, restores the renormalizability of the reheating surface volume by disrupting its fractal structure at macroscopic scales, thereby moderating the conditions for eternal inflation.

Where the Gauss--Bonnet coupling enters the Bondi--Sachs hierarchy

This paper integrates the Bondi–Sachs hierarchy for scalar–Gauss–Bonnet gravity with an arbitrary coupling function to demonstrate that the coupling does not alter the Bondi mass-loss or angular-momentum evolution equations, but instead first manifests dynamically in the $O(r^{-3})$ angular metric coefficient and the $\Psi_0$ Weyl scalar evolution through a cross-term between the scalar charge aspect and gravitational news.

Spin-1 Bulk Local States in AdS/CFT and Carrollian Holography

This paper constructs bulk local states for a massive spin-1 field in AdS $_3$ /CFT $_2$ and three-dimensional Carrollian holography, demonstrating how parity-invariant Proca and Maxwell--Chern--Simons theories emerge from distinct helicity branches and establishing a consistent flat limit that maps AdS states and propagators to their Carrollian counterparts.

Propagation and horizon formation in Einstein--Gauss--Bonnet scalar collapse. I. Characteristic conditions, bounds and formation

This paper investigates scalar collapse in five- and six-dimensional Einstein–Gauss–Bonnet gravity by deriving characteristic conditions and geometric bounds that govern horizon formation, smooth data continuation, and the limits of local geometric uniqueness and continuity in the presence of curvature singularities.

Quantum Algorithms for Finding Vacua in the ADK Landscape

This paper proposes quantum algorithms that reduce the query complexity of finding a vacuum with a small cosmological constant in the ADK string landscape model from $\mathcal{O}(2^{N/2})$ to $\mathcal{O}(2^{N/3})$ by exploiting the linearity of vacuum energy to transform the search into a collision problem, offering a significant computational advantage over classical methods.

The quasinormal modes of Kerr-Newman black holes: a separated approach

This paper demonstrates that a recently discovered exact separation of gravitoelectric perturbation equations provides a highly accurate and practical method for computing Kerr-Newman black hole quasinormal modes, yielding results consistent with coupled-system calculations and offering numerical evidence for spin-label isospectrality even in near-extremal configurations.
