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.

Mass and Force Relations for Extremal E2MD Black Holes

This paper investigates the mass-charge relations and long-range forces between extremal black holes in Einstein-dilaton-Maxwell theory, identifying specific coupling conditions that lead to force cancellation and establishing a general pattern where the sign of the force depends on the product of dilaton couplings, a result supported by exact Toda black hole solutions and linked to the requirement of spacetime regularity.

NN-Photon Amplitudes in EFT from Recursion Relations and Effective Vertices

This paper introduces a recursive framework utilizing CSW-like relations and compact Hafnian-based contact vertices to systematically compute arbitrary tree-level NN-photon helicity amplitudes in general effective field theories, revealing hidden simplicity in helicity-conserving processes and providing explicit results up to 10-point amplitudes for theories like Born-Infeld electromagnetism.

Self-dual S3S_3 gauge theory in 2+1d: lattice model and topological phase transitions

This paper constructs the first lattice model of the non-Abelian S3S_3 quantum double with exact electric-magnetic self-duality realized via lattice translation, revealing a gapless tetracritical Ising edge state and unifying the analysis of its topological phase transitions through category theory, microscopic Hamiltonians, and Chern-Simons-Higgs theory.

3-form dark energy and cosmic birefringence

This paper investigates how 3-form dark energy coupled to photons via dimension-4 and dimension-6 operators can explain observed cosmic birefringence, revealing that while the dimension-4 operator offers a viable explanation sensitive to initial conditions, the dimension-6 operator requires unrealistically large couplings, with both scenarios producing birefringence profiles that can either mimic or be distinguished from axion-like particle models depending on early-universe field configurations.

GOOFy-compatible 3HDMs and beyond

This paper introduces a sign-orbit technique to systematically classify GOOFy-compatible quadratic structures in multi-Higgs models, demonstrating that such structures exist only under specific group-theoretic conditions and revealing that the renormalisation-group stability of the r0→−r0r_0 \to -r_0 manifold is a unique consequence of SU(2)SU(2) algebra rather than a generic feature.

Surviving correlations across a horizon: reflected entropy for bosonic fields in non-inertial frames and black hole spacetimes

This paper investigates the reflected entropy and Markov gap for bosonic fields across event horizons in non-inertial frames and Schwarzschild black holes, revealing that while bosonic entanglement vanishes asymptotically, reflected entropy saturates at a non-zero floor and inter-wedge entropy diverges linearly with the squeezing parameter—a sharp contrast to the bounded behavior observed in fermionic systems.

Coherent and Stochastic Axion Dark Matter from Thermal Relaxation

This paper proposes a unified framework where thermal relaxation of axions in an expanding plasma partitions dark matter into coherent and stochastic components, resulting in a relic population with lower mean momentum, reduced isocurvature, and distinct structural properties compared to standard equilibrium scenarios.
