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.
Particle cosmology integrates the physics of fundamental particles with the study of the cosmos, utilizing the early Universe as a high-energy laboratory and cosmological observations to test theoretical frameworks like inflation, baryogenesis, and Dark Matter.
This paper demonstrates that the space-like singularities appearing in certain time-dependent backgrounds of two-dimensional string theory are artifacts of the strict double scaling limit, as a full matrix model treatment with non-linear terms reveals that the system undergoes a quantum quench leading to a stable, power-law relaxation to a time-independent equilibrium state rather than a true singularity.
This paper investigates how generalized no-scale inflationary models, characterized by modified field space curvature or non-minimal couplings, can overcome the suppression of inflaton decays to Standard Model fields to enable efficient reheating and yield distinct predictions for the spectral index and tensor-to-scalar ratio.
This paper demonstrates that magnetic quivers provide the essential information required to determine the Drinfeld center of symmetry topological field theories (SymTFTs) associated with absolute theories, a connection grounded in their shared objective of generalizing homological mirror symmetry.
This paper employs categorical algebraic geometry to explore how abelianisation can facilitate the embedding of Beyond the Standard Model scenarios within supersymmetric frameworks derived from string theory.
This paper provides a concrete and computable realization of the ER=EPR conjecture by deriving the Einstein-Rosen bridge from quantum entanglement in the thermofield double CFT, explicitly identifying the wormhole's Bekenstein-Hawking entropy as entanglement entropy and quantitatively verifying Van Raamsdonk's conjecture on spacetime emergence.
This paper investigates axion mass mixing in the string axiverse from a bottom-up perspective, identifying that maximal mixing occurs when all axion-like particle masses are smaller than the QCD axion mass with no degeneracies and uniform decay constant hierarchies, while energy transfer is restricted to the pair of axions with the closest masses.
Using large-scale tensor network and exact diagonalization methods, the authors investigate an "odd" variant of the 2D Ising Fradkin-Shenker model to reveal a complex phase diagram featuring distinct valence bond solid and deconfined phases, culminating in an exotic multicritical point where confinement, Higgs condensation, and spontaneous duality symmetry breaking occur simultaneously.
This paper proposes a unified theoretical framework for dense QCD matter in the Veneziano large- limit, identifying four distinct phases—including two types of partial deconfinement driven by string or baryon condensation—and suggesting that their interplay naturally gives rise to the QCD critical point.
This paper investigates various holographic solutions, including supersymmetric vacua, RG flows, conformal interfaces, and black string/hole geometries, within five-dimensional gauged supergravity with an gauge group, which arises from a consistent truncation of M-theory on and describes dualities to SCFTs and lower-dimensional superconformal theories.
