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 ground state degeneracy of infinite-component Chern-Simons-Maxwell theories with block-Toeplitz K matrices, classifying its diverse growth patterns and linking them to the roots of the associated determinant polynomial to distinguish between gapped and gapless phases and identify conditions for foliated fracton orders.
This paper utilizes a combination of "magnetic" and "electric" Ehlers-Harrison transformations on a Minkowski seed to derive a new type D electromagnetic swirling universe and four novel asymptotically nonflat type I spacetimes, providing detailed geometric analyses, singularity checks, and connections to known solutions like the Melvin and Reissner-Nordström-NUT metrics.
This paper investigates non-singular cosmological bouncing solutions in higher-order torsion gravity by reconstructing the gravitational Lagrangian for five distinct bounce scenarios across various matter phases, demonstrating that these models naturally satisfy observational constraints and avoid singularities through geometric mechanisms that violate the null energy condition without requiring ad hoc matter fields.
This paper demonstrates that by extending the vacuum gravity framework with infinite quasi-topological higher curvature corrections, one can construct regular black hole solutions in four dimensions that possess vanishing inner horizon surface gravity, thereby eliminating classical mass inflation instabilities.
This paper demonstrates that standard thermal theory overestimates the decay rate of metastable vacua at moderate temperatures because the nucleation process violates thermal equilibrium in weakly coupled field theories, though the standard rate is recovered at sufficiently low temperatures.
This paper investigates how new scalar and vector mediator particles affect the ratio of electromagnetic form factors in electron-proton scattering, establishing coupling strength bounds that align with constraints from other independent experiments.
This paper demonstrates that the spherically symmetric collapse of a uniform dust star in Quadratic Gravity inevitably leads to horizon formation and a singularity that forms faster than in General Relativity, despite the theory's rich phase space of static solutions.
This paper constructs a non-perturbative Noether realization of asymptotic higher spin symmetries in gravity by introducing a symmetry algebroid that incorporates radiation and demonstrates that the associated charges are conserved in the absence of radiation, provided the symmetry parameters evolve according to equations of motion dual to the asymptotic Einstein equations.
This paper applies finite-size scaling to net-baryon cumulant ratios from Au+Au collisions across the Beam Energy Scan Phase I range, revealing a universal collapse consistent with 3D Ising critical behavior and pinpointing the QCD critical end point at approximately GeV ( MeV, MeV).
This paper demonstrates that global symmetries are violated in Hawking radiation by modeling black holes as non-isometric codes, which cause non-zero overlaps between states of different charges and yield Renyi entropies consistent with the quantum extremal surface formula.
