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.

Gravitational Memory Beyond Null Infinity through Finite-Distance Carrollian Screens

This paper establishes a quasilocal Carrollian framework for gravitational memory at finite distances using null hypersurfaces, demonstrating through Robinson--Trautman spacetimes that the standard Bondi displacement memory emerges as the universal asymptotic limit of a broader geometric response that retains near-zone information and exhibits non-monotonic energy fluxes in the presence of a cosmological constant.

Domain Walls From Confining Bubbles: SU(Nc)SU(N_{c}) Yang Mills at Finite θ\theta

This paper investigates the confinement phase transition in SU(Nc)SU(N_c) pure Yang-Mills theory at finite θ\theta using the Improved Holographic QCD model, demonstrating that the critical temperature decreases with θ\theta to reduce supercooling and analyzing the resulting dynamical formation of domain walls and their potential gravitational wave signatures.

Torsionful Killing-Yano Forms under T-Duality: Transformation Conditions and Emergent Isometries

This paper derives compact, coordinate-free transformation laws for torsionful Killing-Yano forms under Abelian T-duality, demonstrating the preservation conditions for Killing 1-forms and providing a generalized-geometric interpretation of emergent isometries through explicit applications to various spacetimes including S3S^3, Schwarzschild, and the Nappi-Witten plane wave.

Defrosting the Born-Infeld dyonic frozen star with tachyon matter: spectrum of oscillations

This paper simplifies the derivation of the oscillation spectrum for a "defrosted" Born-Infeld dyonic frozen star by using the underlying Lagrangian instead of fluid approximations, thereby confirming that sound velocities scale linearly with the defrosting parameter γ\gamma while lifetimes scale as 1/γ21/\gamma^2, and ensuring the consistency of perturbation equations for arbitrary non-spherical deviations.

3d SUSY enhancement with non-trivial Coulomb branch via 4d N=2\mathcal{N}=2 SCFT

This paper presents the first construction of a 3d N=2\mathcal{N}=2 Chern-Simons matter theory that flows to a 3d N=4\mathcal{N}=4 SCFT with a non-trivial Coulomb branch (specifically the orbifold C2/Z2\mathbb{C}^2/\mathbb{Z}_2) via the RR-twisted reduction of the (A2,D4)(A_2,D_4) Argyres--Douglas theory, while also identifying a novel mixing between 4d R-charges and emergent 3d flavor charges.

Holographic Soliton Crystals for Dense Nuclear Matter and Neutron Stars

This paper constructs a nuclear-matter equation of state for neutron stars using a holographic Witten-Sakai-Sugimoto model with a face-centered cubic soliton crystal approximation, which successfully reproduces saturation properties and NICER-compatible observables while correcting the deficiencies of previous homogeneous approximations.
