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.

Taming the infrared in de Sitter space: autonomous equations, stochastic approach, and Borel resummation

This paper investigates the divergent perturbative series of correlation functions for a massless, self-interacting scalar field in de Sitter space by applying autonomous equations to both the original series and their Borel-Le Roy transforms, demonstrating that the latter approach yields results that substantially better match the stochastic picture while also offering new derivations and methods for extracting perturbative coefficients.

Joint distributions of eigenvectors of symmetric random tensors

This paper employs quantum field theoretical methods to compute the joint distributions of arbitrary numbers of eigenvectors for real and complex symmetric random tensors, deriving their random matrix representations and large-dimension asymptotics to demonstrate a universal behavior across tensor geometries that extends previous findings on mean distributions.

Double fibration in G-theory and the cobordism conjecture

This paper investigates Type IIB compactifications with spatially varying fluxes and dilaton profiles within dynamical cobordism, demonstrating that End of the World branes arise to trivialize specific cohomology classes and that the associated bordism group necessitates additional non-perturbative objects to cancel these classes, thereby revealing a mathematical structure linking energy scales to the emergence of perturbative and non-perturbative physics.

Fifth-Force Constraints from UV-Complete Scalar-Tensor Gravity

This paper demonstrates that requiring UV completeness in a specific class of scalar-tensor gravity models restricts their infrared parameters to a narrow region, thereby ruling out a portion of the parameter space currently accessible to fifth-force experiments and offering a direct path to falsify these theories.

Infrared spectra of some strongly--coupled chiral gauge theories

This paper investigates several simple asymptotically-free chiral gauge theories to reveal surprisingly rich infrared effective structures, RG flows, and light spectra by applying recent developments in generalized symmetries and anomaly matching alongside established knowledge of vectorlike theories.

Distinguishing Higgs portal and neutralino dark matter via vector boson fusion

This paper demonstrates that vector boson fusion processes at the LHC can distinguish between Higgs portal and neutralino dark matter scenarios with over $5\sigma$ confidence by exploiting characteristic differences in jet transverse momentum and kinematic variables like $\Delta\eta$ and $\Delta\phi$ .

Axion-Scalar Dynamics: from the Distance Conjecture to Cosmic Acceleration

This paper investigates axion-scalar cosmology in type IIB/F-theory flux compactifications, confirming a proposed extension of the Distance Conjecture for infinite distance limits while revealing that finite distance limits in these models unexpectedly exhibit asymptotic accelerated expansion despite trajectories having infinite length.

Family Unification in $SO(16)$ Grand Unification

This paper proposes a six-dimensional $SO(16)$ grand unified model that unifies the three Standard Model gauge symmetries with an $SU(3)$ family symmetry, successfully accommodating three chiral fermion generations while ensuring anomaly cancellation through vectorlike bulk fields and localized 4D fermions, and exhibiting a weakening gauge coupling at high energies.

Applying the Worldvolume Hybrid Monte Carlo method to the Hubbard model away from half filling

This study demonstrates that the Worldvolume Hybrid Monte Carlo method effectively mitigates the severe numerical sign problem in the two-dimensional Hubbard model away from half-filling, successfully computing physical observables on $6 \times 6$ and $8 \times 8$ lattices where standard determinant quantum Monte Carlo methods fail.

Enhancing the ergodicity of Worldvolume HMC via embedding Generalized-thimble HMC

This paper proposes and validates a hybrid algorithm that embeds Generalized-thimble HMC within Worldvolume HMC to overcome ergodicity limitations in thin-layer simulations, thereby enabling efficient, large-scale studies of the doped Hubbard model with controlled statistical errors.
