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.

The Wilson-line-dressed charged sector of scalar QED: superselection and the infraparticle

This paper develops a manifestly gauge and Lorentz invariant perturbative framework to demonstrate that electrically charged states in scalar QED are superselected by the orientation of their Wilson-line dressings due to "cloud orthogonality," while within a single sector, the absence of a sharp mass pole reveals an infraparticle structure characterized by a power-law spread in proper time.

Cycles Without End: An Ekpyrotic Braneworld Bounce with a Kinetically Coupled Entropic Mechanism

This paper presents an explicit cyclic cosmology model that resolves the historical challenges of singular bounces, blue spectral tilt, and entropy accumulation by utilizing a Randall-Sundrum brane with a timelike extra dimension and a kinetically coupled entropic field to achieve a non-singular bounce, a nearly scale-invariant spectrum, and entropy dilution through dark energy.

Solar Capture Tests of Inelastic Dark Matter after the LZ High-Recoil Event

This paper demonstrates that while Solar capture constraints definitively exclude the thermal Higgsino interpretation of the recent LZ high-recoil event, they do not generically rule out other endothermic dark matter models, such as thermal pseudo-Dirac fermions or neutron-philic spin-dependent scattering, which remain viable despite being significantly below current IceCube limits.

Inelastic Self-interacting Dark Matter and LUX-ZEPLIN 248 keV Event in a Dirac Modular Inverse Seesaw

This paper proposes a novel $A_4$ modular symmetry framework that unifies Dirac neutrino mass generation with inelastic self-interacting dark matter, successfully explaining the LUX-ZEPLIN 248 keV event while predicting a stochastic gravitational wave background from the annihilation of cosmological domain walls.

Dual N=1 Lagrangians for Argyres-Douglas theories

This paper introduces a new class of four-dimensional $\mathcal{N}=1$ $SU(2)^n$ quiver gauge theories with flip fields that flow to various $\mathcal{N}=2$ Argyres-Douglas theories in the infrared, providing dual descriptions to previously known $Sp(n)$ and $SU(n+1)$ realizations by exchanging the rank and the number of nodes in the quiver diagram.

Darboux Isospectrality Constraints on Quasinormal Modes Deformed by Bumps

This paper demonstrates that the common practice of adding identical Gaussian or Pöschl-Teller bumps to both Schwarzschild Regge-Wheeler and Zerilli potentials violates Darboux isospectrality constraints, and it proposes two consistent alternative prescriptions—using the profile as a Darboux generator or solving for a partner via the Riccati equation—to avoid spurious axial-polar splitting in quasinormal modes.

Connecting Regge factorization and Collins-Soper evolution

This paper establishes a unified framework connecting Regge factorization and Collins-Soper-Sterman factorization by demonstrating a direct relationship between the Collins-Soper kernel and the Regge trajectory, thereby bridging high-energy and low-transverse-momentum resummation techniques.

Stationary states for a particle in a box with slanted walls

This paper investigates the quantum mechanical problem of a particle in an infinite potential well with slanted walls, deriving energy eigenvalues via Airy functions and demonstrating that the system exhibits unique asymptotic energy spacing and confinement behaviors that surpass standard models in fulfilling Bohr's correspondence principle.

Can one hear the shape of a black hole singularity?

This paper demonstrates that the Kasner exponents and chaotic transitions characterizing the near-singularity geometry of asymptotically AdS black holes can be uniquely determined from the large overtone behavior of their quasinormal frequencies, effectively allowing one to "hear" the shape of the singularity.

Exact spin form factors and correlations at a massive Kramers-Wannier interface

This paper determines exact finite-volume spin form factors and two-point correlations for a massive Kramers-Wannier interface in the scaling Ising model by combining complementary lattice realizations, factorized Fredholm determinants, and independent numerical confirmations to characterize the interface separating ordered and disordered phases.
