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.

New soliton solutions for Chen-Lee-Liu and Burgers hierarchies and its Bäcklund transformations

This paper formulates positive and negative flows of the Chen-Lee-Lee-Liu model and Burgers hierarchy using Riemann-Hilbert-Birkhoff decomposition, derives their soliton solutions and vertex operators via a dressing method for both zero and constant non-zero vacua, and introduces gauge-Bäcklund transformations to generate additional multi-soliton solutions through interactions with integrable defects.

Review of strongly coupled regimes in gravity with Dyson-Schwinger approach

This paper employs the Dyson-Schwinger technique to analyze de-Sitter, quadratic $\mathcal{R}^2$ , and non-minimally coupled scalar gravity theories, identifying conformally flat metric solutions and demonstrating how non-minimal coupling can hinder a sequence of cosmological phase transitions originating from conformal symmetry breaking.

Thermodynamics of Hairy Black Holes in Quantum Regimes: Insights from Horndeski Theory

This paper investigates non-perturbative quantum gravitational corrections to the thermodynamics of $n$ -dimensional Schwarzschild–Tangherlini–Anti-de Sitter black holes, revealing that these effects induce a Hawking–Page transition, suppress specific heat magnitude, and reverse the sign of average quantum work during evaporation, thereby qualitatively altering the phase structure and energetics beyond what perturbative corrections can capture.

M-theory and T-geometry: Higgs branch moduli and charged matter

This paper constructs novel 3d $\mathcal{N}=2^{\ast}$ and $\mathcal{N}=4^{\ast}$ gauge theories via M-theory on non-compact 8d "T-geometries" (fibrations of $\mathbb{R}^{4}/\Gamma_{ADE}$ over Bieberbach manifolds), demonstrating that nilpotent Higgsing induced by permutation groups restores supersymmetry and encodes both Higgs branch moduli and localized non-chiral charged matter within Slodowy slices.

Meson mixing effects on the speed of sound in isospin-imbalanced matter

Using the two-flavor Linear Sigma Model with quarks, this study demonstrates that meson mixing effects and the resulting Goldstone mode dynamics in isospin-imbalanced matter produce a pronounced peak in the speed of sound whose position and width align well with lattice QCD simulations.

Threshold asymptotics and decay for massive Maxwell on subextremal Reissner--Nordström

This paper establishes the precise late-time asymptotics and decay rates for the neutral massive Maxwell (Proca) equation on subextremal Reissner--Nordström exteriors by developing a threshold spectral theory that resolves the even-sector coupling into distinct polarization channels, thereby proving logarithmic decay for the full field while identifying a universal $t^{-5/6}$ polynomial tail for its radiative component.

Gravitational mass generation and consistent non-minimal couplings: cubics and quartics of a massive vector

This paper proposes a modified Noether procedure that introduces a vector field coupled to a graviton at the quadratic level, resulting in a gauge-invariant vector mass and novel consistent interactions up to quartic order, thereby offering a potential geometric interpretation to evade the strict uniqueness constraints of spin-2 interactions.

Mixed-State Topological Phase: Quantized Topological Order Parameter and Lieb-Schultz-Mattis Theorem

This paper extends the concept of symmetry-protected topological phases to one-dimensional mixed-state regimes with strong U(1) and weak $\mathbb{Z}_2$ symmetries by introducing a quantized topological order parameter and demonstrating how these findings allow for a generalization of the Lieb-Schultz-Mattis theorem to mixed states independent of spectral gaps or lattice Hamiltonians.

Two-component dark matter from a flavor-dependent $U(1)$ gauge extension

This paper extends the phenomenological analysis of a flavor-dependent $U(1)_X$ gauge extension of the Standard Model by relaxing the assumption of a strong scalar hierarchy, thereby revealing a new two-component dark matter scenario comprising both fermionic and scalar particles alongside the previously studied purely fermionic case, and identifying viable parameter spaces consistent with relic density and direct detection constraints.

On the ultraviolet behavior of the invariant charge in quantum electrodynamics

This paper investigates the ultraviolet behavior of the invariant charge in quantum electrodynamics, demonstrating that a modified real-part definition avoids the Landau pole singularity and utilizing $1/N$ perturbation theory in an imaginary-charge model to derive specific asymptotic corrections that likely extend to standard and other non-asymptotically free QED models.
