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.
This paper investigates the one-loop effective potential of the r0 (or "GOOFy") symmetric two-Higgs Doublet Model and a minimal symmetric model, concluding that the symmetry remains valid at the one-loop level provided the UV cutoff squared transforms non-trivially under r0 and the minimal model includes two real fields.
This paper establishes the complete equivalence between two Schwinger-Keldysh effective field theory approaches for non-Abelian charge transport near thermal equilibrium, extends both formalisms to satisfy dynamical Kubo-Martin-Schwinger symmetry to all orders in , and provides a systematic framework for analyzing transport and fluctuations through clarified power-counting rules.
This paper proposes that the thermal entropy of 2d and 3d black holes arises from string entanglement between folded strings in the dual sine-Liouville CFT, where a worldsheet replica method reveals a vertex operator contribution that matches the low-temperature entropy in large dimensions and a remaining replica contribution that likely accounts for the total entropy.
This paper establishes the Flat/CCFT correspondence by deriving the entanglement entropy of highly excited states in 2d Carrollian/Galilean CFTs, which matches holographic results from 3D Einstein gravity and confirms the Eigenstate Thermalization Hypothesis while defining a precise dictionary between boundary and bulk parameters.
This paper employs machine learning techniques to revisit the fermion mass problem in the Georgi-Glashow $SU(5)$ grand unified theory, demonstrating that models incorporating a 24-dimensional field or a continuous parameter offer a more "beautiful" (closer to the original model) resolution to the observed fermion mass spectrum than those using a 45-dimensional field.
This paper utilizes lattice QCD data to demonstrate that the gluon gravitational form factors of various hadrons are well-described by a -meson pole consistent with dilaton effective theory, thereby providing further evidence that QCD dynamics may be governed by an infrared fixed point.
This paper introduces unit-invariant generalizations of von Neumann entanglement entropy based on the Unit-Invariant Singular Value Decomposition (UISVD), demonstrating their stability and physical relevance across diverse frameworks including biorthogonal quantum mechanics, random matrix theory, and Chern-Simons theory.
This paper demonstrates that for flat minisuperspace models with closed Universes, a specific class of operator orderings in the Wheeler-DeWitt equation, which are uniquely determined by path-integral measures and correspond to field redefinition Jacobians, yields physically equivalent quantum theories with identical observables and positive definite inner products.
This paper proposes and constructs a consistent integral transformation for celestial gluon amplitudes, inspired by closed string scattering, which maps celestial coordinates to new complex variables and establishes the necessary conditions for global conformal invariance in MHV amplitudes.
This paper applies resurgence theory to the 't Hooft-Polyakov monopole, demonstrating that its differential equations admit a uniformly convergent global perturbative expansion around simple universal non-perturbative backgrounds, thereby providing precise analytic control over the monopole's profile functions and numerical parameters for any coupling ratio.
