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 proposes a method to directly compute hadronic form factors at complex momenta from lattice QCD position-space correlators using a bilateral Laplace transform, thereby extending the accessible kinematic domain to improve precision in observables like the charge radius without requiring analytic continuation or solving inverse problems.
This paper conjectures and provides evidence across free, holographic, and interacting conformal field theories that the universal logarithmic coefficient for capacity of entanglement is bounded below by the corresponding entropy coefficient at conformal interfaces, while demonstrating that capacity offers independent diagnostic information capable of distinguishing interfaces with identical entropy and energy transmission.
This paper introduces "domestic geometry" as a unifying framework for describing the gauge couplings of supersymmetric 4d effective theories and speculates on extending this geometric approach to non-supersymmetric gravity within the swampland program.
This paper demonstrates that the thermal branch of black holes in the BMN matrix model terminates at a critical point via a continuous transition to a confined phase, characterized by a universal neck geometry and the absence of the previously hypothesized first-order phase transition.
This paper investigates the Simpson-Visser regularization of the quantum Oppenheimer-Snyder-Datt black hole, demonstrating how the combined parameters and govern a rich phase structure ranging from regular black holes to traversable wormholes, while uniquely distinguishing the effects of the quantum correction on orbital dynamics and shadow from the topological and wave-propagation signatures of the bounce parameter .
This paper proposes a testable framework for consistent semiclassical gravity where quantum systems source gravitational fields only upon environment-induced decoherence, offering distinct experimental predictions for the BMV experiment and quantum circuits while utilizing generalized quantum causal models to explore how gravity may emerge from quantum field theory.
This paper derives exact solutions for the curvature power spectrum and bispectrum in a two-field inflationary model with arbitrary constant mixing and unequal sound speeds, revealing how the sound-speed ratio governs distinct enhancement regimes, oscillatory behaviors, and modifications to cosmological collider signals.
This paper extends Tomita-Takesaki theory to analyze soft radiation and memory effects, demonstrating that black holes decohere their environment by acting as optimal observers that distinguish quantum states via long-range fields across the horizon.
This paper demonstrates that near-threshold intra-tower decays of Kaluza-Klein gravitons follow a -wave () scaling rather than the previously assumed -wave () behavior, which effectively rules out these gravitons as dark matter in a flat dark dimension and necessitates a significantly smaller extra-dimensional radius to satisfy cosmological constraints on gamma-ray backgrounds and reheating temperatures.
This paper extends the AS² cosmological-state construction to multiple holographic CFTs by modeling their junction with random tensors, demonstrating that the resulting "booklet cosmological states" encode information in a way that allows any two boundary arms to recover a central closed universe, thereby establishing a connection to quantum error correction.
