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 study demonstrates that future lepton colliders, specifically the Future Circular Collider and a multi-TeV muon collider, can significantly improve constraints on lepton dipole moments by several orders of magnitude through various production and decay channels, thereby offering a powerful probe for new physics beyond the Standard Model.
This paper develops a composite-operator renormalization and matching formalism within Soft de Sitter Effective Theory to compute the first next-to-leading order (two-loop) quantum correction to the diffusion term in the stochastic inflation Fokker-Planck equation.
This paper investigates the sensitivity of the Light Dark Matter eXperiment (LDMX) to MeV-GeV axions and dark photons, demonstrating that its near-target tracking capabilities could effectively close the long-standing experimental blind spot in the sub-100 MeV mass range where current prompt-decay and beam-dump searches are ineffective.
This paper constructs exact spherically-symmetric black hole solutions in dimensions for Einstein gravity coupled to two Maxwell fields and a dilaton by mapping the equations of motion to one-dimensional Toda equations of all rank-2 Lie groups, deriving new solutions for and cases, and verifying that their thermodynamic properties can be determined without explicitly solving for the metric.
Using large-scale quantum Monte Carlo simulations, this paper establishes the existence of a zero-temperature charge-4e superconducting phase in the attractive SU(4) Hubbard model and demonstrates that the transition from charge-2e to charge-4e superconductivity is governed by an unconventional deconfined quantum pseudocriticality described by an Sp(4) gauge-Higgs theory.
This paper establishes a comprehensive framework connecting intrinsic Carrollian fermions, small speed-of-light expansions of relativistic Dirac theory, and light-cone dynamics by deriving Carrollian actions from relativistic limits and demonstrating how Carrollian fermions in dimensions relate to relativistic fermions in both and dimensions.
This paper derives a gauge-covariant single-band lattice model on the non-rotating BTZ black hole background to demonstrate how the interplay between AdS curvature and horizon size governs the fragmentation of Hofstadter's butterfly and the suppression of magnetic and Aharonov-Bohm responses through near-horizon state localization.
This paper derives analytical expressions for the one-loop quantum corrections to the Casimir effect and topological mass generation for a self-interacting real scalar field between rough parallel plates at low temperatures, utilizing WKB methods and -function regularization to account for both geometric perturbations and finite thermal effects.
This paper presents a hydrodynamic analog of the Klein Paradox using a linear elastic medium to demonstrate that vacuum instability and pair production arise from mechanical breakdown under supercritical stress, thereby offering a concrete pedagogical model for visualizing these quantum field theory phenomena.
This paper demonstrates that in the double-scaling limit of the SYK model, the emergent algebraic description of Kourkoulou-Maldacena pure states transitions from a mixed Type II factor to a pure Type I algebra when augmented with state-adapted dressed operators, thereby restoring access to the underlying microscopic purity and providing a concrete framework for understanding black hole interiors and closed universes.
