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.
Using light-front holographic QCD, this paper demonstrates that the nucleon's gravitational form factor is significantly suppressed at finite momentum transfer due to a fundamental cancellation arising from an antisymmetric factor in the longitudinal dynamics, which serves as a signature of the nucleon's dominant S-wave character.
This paper proposes a systematic framework using maximum-entropy reweighting and precision moments of energy flow polynomials to upgrade parton-shower event samples with higher-accuracy theoretical constraints, thereby restoring physical behavior and improving predictions across a broad range of observables while preserving full event-level exclusivity.
This paper refines theoretical predictions for light-by-light scattering by improving two-loop helicity amplitudes with asymptotic expansions and Coulomb resummation, providing state-of-the-art Standard Model cross-section calculations and a new Monte Carlo event generator named LbLatNLO.
This paper applies a postmodern and post-postmodern lens to semiclassical gravity, arguing that the inherent tension between observer-dependent and observer-free descriptions of closed universes should be embraced as a fundamental feature of quantum gravity rather than resolved.
This paper presents the discovery of infinitely many soliton-like solutions in a deformed sine-Gordon theory on -dimensional anti-de Sitter space () and single solitonic solutions in de Sitter, Lobachevsky, and spaces, while demonstrating how these curved-space solutions relate to flat-space limits and supersymmetric theories.
This paper resolves the thermodynamic limitations of event horizons by demonstrating that quasi-local horizons allow for a robust formulation of the first and second laws of black hole mechanics applicable to dynamical black holes arbitrarily far from equilibrium, thereby identifying black hole entropy with the area of marginally trapped surfaces rather than the event horizon.
This paper uses numerical techniques on BFSS Matrix theory at strong coupling to demonstrate that the general relativistic force between two static objects emerges as an entropic force, thereby validating Verlinde's entropic gravity and the fuzzball paradigm while suggesting that black hole interiors are better described by AdS space rather than a traditional singularity.
This paper establishes a No-Go theorem proving that within analytic gravitational theories, treating quantum corrections solely as effective matter sources is insufficient to resolve singularities in gravitational collapse, thereby necessitating non-analytic action modifications or vanishing effective energy density at high densities for successful singularity resolution.
This review provides a pedagogical introduction to Lieb-Schultz-Mattis (LSM) anomalies and anomaly matching, extending the discussion from quantum spin chains to higher dimensions, disordered systems, fermionic systems, and cases involving nontrivial symmetry-protected topological phases.
This paper investigates phase transitions in anti-de Sitter black holes coexisting with anisotropic matter fields, demonstrating their resemblance to Reissner-Nordström black holes and analyzing the correlation between these thermodynamic phases and the Lyapunov exponents derived from unstable null geodesics.
