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 demonstrates that in quasi-topological gravity, neutron stars can achieve compactness exceeding the black-hole limit and exhibit enhanced radial stability at high central densities, establishing them as theoretically viable ultra-compact configurations.
Using quantum field theory of linearized gravity, the paper demonstrates that the Berry curvature of right- and left-handed gravitons induces a spin Hall effect in curved spacetime, resulting in a helicity-dependent energy current splitting that is exactly twice the magnitude of the corresponding effect for photons.
This paper proposes the rare Standard Model Higgs decay as a probe of Higgs interactions, calculating its branching ratio of approximately and demonstrating that it can be observed with high significance at both the High-Luminosity LHC and the ILC using multivariate analysis techniques.
This paper presents a recursive perturbative expansion of the Kerr black hole metric in harmonic gauge as a double series in Newton's constant and the spin parameter, detailing the challenges of re-summing the series into a closed form and addressing related dimensional regularization issues.
This paper argues that near the surface of an Exotic Compact Object, the vacuum Einstein equations induce chaotic metric oscillations analogous to cosmic billiards, where sign-changing potential walls cause compact directions to collapse into zero size, naturally transitioning the geometry into the interior of string theory fuzzballs.
This paper aims to bridge a gap in pedagogical literature by demonstrating the application of the Hamilton-Ostrogradski formalism to the Pais-Uhlenbeck oscillator and coupled oscillators, providing a foundation for advanced classical mechanics courses.
This paper proposes a hidden-sector dark matter model where the dark matter and Standard Model decouple at high temperatures yet evolve to similar temperatures at freeze-out, allowing for the observed relic abundance with standard annihilation cross sections while rendering direct detection and collider signals potentially unobservable due to extremely weak couplings.
This paper proves that a non-trivial quantum Yang-Mills theory must possess a mass gap arising from a constant tadpole term in the gluon self-energy, a conclusion derived from a novel constraint on QCD solutions within the Slavnov-Taylor identity framework that preserves perturbative renormalizability while addressing the Jaffe-Witten theorem.
This paper investigates the Dynamical Casimir Effect for a real scalar field in dimensions interacting with a time-dependent Dirichlet surface by employing a perturbative expansion up to fourth order to derive general expressions for pair creation probabilities and analyze the influences of space-time dimensionality and non-linear effects.
This paper utilizes effective field theory consistency relations to demonstrate that current constraints on the effective gravitational constant derived from gravitational wave observations are consistent with, and in the case of GW170817 comparable to, those obtained from large-scale structure surveys, thereby validating these independent probes of dark energy.
