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.

Crosscap states and duality of Ising field theory in two dimensions

This paper proposes two distinct crosscap states for the 2D Ising field theory related by Kramers-Wannier duality, derives their Majorana and bosonized representations to compute correlation functions, and utilizes conformal perturbation theory to demonstrate the monotonicity of Klein bottle entropy under relevant perturbations, thereby establishing a general framework for studying perturbed 2D conformal field theories on non-orientable manifolds.

On Intersecting Conformal Defects

This paper investigates the physics of two and three mutually intersecting conformal defects in general dimensions, deriving beta functions for edge interactions, analyzing the angle-dependent edge anomalous dimension, and computing the corner anomalous dimension for trihedral corners and three-line configurations as higher-dimensional analogs of the cusp anomalous dimension.

Off-shell phase diagram of BPS black holes in AdS $_5$

This paper constructs the off-shell free energy and phase diagram of supersymmetric black holes in AdS $_5$ , incorporating four-derivative corrections and utilizing AdS/CFT duality to propose effective potentials that capture the thermodynamic phases of the dual boundary gauge theory.

Universality of entanglement in gluon dynamics

This paper demonstrates that in pure $SU(N)$ gauge theories, gluon polarization entanglement arises exclusively from opposite initial polarizations and reaches a universal maximum at a 90-degree scattering angle independent of the gauge group, provided the precise balance between three- and four-gluon vertices is maintained.

Exact critical exponents of the Motzkin and Fredkin Chains

This paper analytically determines the exact critical exponents $\eta=1/2$ and $\nu_\pm=2/3$ for the Motzkin and Fredkin chains by utilizing a transfer matrix derived from their matrix product state representation combined with renormalization group analysis, thereby overcoming previous limitations in characterizing their exotic quantum phase transition.

A Novel On-Shell Recursive Relation

This paper introduces a novel on-shell recursive framework for biadjoint and pure Yang-Mills theories, derived from double-cover CHY factorization, which reconstructs amputated currents and reformulates BCJ numerators into an explicitly on-shell factorized form.

Massive Spinor Helicity Amplitudes, Cross Sections, and Coalescence

This paper advances the spinor helicity formalism for massive particles by detailing their projective-geometry kinematics, deriving two new methods for calculating cross sections, and interpreting mass acquisition as the localization of worldlines in twistor theory to unify spacetime and particle content.

The 4-fold Pandharipande--Thomas vertex and Jeffrey--Kirwan residue

This paper introduces a Jeffrey--Kirwan residue contour integral formalism that unifies the computation of K-theoretic equivariant Pandharipande--Thomas and Donaldson--Thomas 4-vertices by varying the reference vector, while also exploring their correspondence and generalizations in the context of 4-folds.

Quantum Corner Polynomials: A Generalization of Super Macdonald Polynomials and Their VOA Correspondence

This paper introduces quantum corner polynomials as a generalization of Sergeev-Veselov super Macdonald polynomials, establishes their correspondence with quantum corner vertex operator algebras, and provides a rigorous proof of their partial symmetricity.

A New Supersymmetry Index for the D1-D5 CFT

This paper proposes a new one-parameter supersymmetry index for the D1-D5 CFT on $T^4$ using a Schur-Weyl duality formulation, which successfully matches supergravity results below the black-hole threshold and reveals previously invisible microstate sectors above it, offering finer-grained insights than the standard modified elliptic genus.
