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 derives recurrence relations for leading logarithmic all-loop quantum corrections in $SO(N)$ symmetric scalar field theories within curved spacetime, formulates a corresponding system of renormalization group equations for the effective potential in the large limit, and applies these results to analyze power-like potentials in the Jordan frame for inflationary cosmology.
This paper presents the first example of a nonlocal, Lorentz-invariant quantum field theory that simultaneously satisfies renormalizability, unitarity, and causality while violating CPT symmetry, offering a viable framework for explaining the universe's baryon asymmetry.
This paper employs Bayesian inference within a unified framework to constrain the neutron star equation of state across hadronic, crossover, and quark phases, revealing that current multi-messenger data strongly limit low-to-intermediate density nuclear symmetry energy parameters while leaving high-density quark matter properties largely unconstrained until next-generation observations become available.
This paper demonstrates that the gauge dependence of one-graviton-loop corrections to the effective field equation of a massless, minimally coupled scalar in de Sitter space cancels out when contributions from all diagram classes, including one-loop corrections to external mode functions, are consistently collected, thereby supporting the construction of gauge-independent cosmological quantum-gravitational observables.
This paper provides a comprehensive review of supersymmetry, supergravity, and non-perturbative gauge theory dynamics, tracing the theoretical framework from fundamental algebraic structures and the Seiberg-Witten solution to string theory applications and a detailed analysis of the KKLT moduli stabilisation mechanism in the context of de Sitter vacua and the swampland conjecture.
This paper investigates charged massive scalar field perturbations on the Kerr-EMDA black hole background by deriving exact analytical solutions in terms of confluent Heun functions to determine a mass-dependent resonant frequency spectrum, a parameter-dependent entropy quantization that diverges at extremality, and the first closed-form greybody factor for this geometry, thereby revealing how electromagnetic coupling and dilaton deformation fundamentally alter the black hole's wave scattering and thermodynamic properties compared to standard Kerr and Kerr-Newman cases.
This paper establishes a new high-precision analytic approximation for the vacuum mutual information in arbitrary -dimensional conformal field theories by leveraging modular flow and twist operator contributions from primary fields, a method validated against known results and applied to previously unsolved cases like the Maxwell field.
This paper investigates a dark matter model consisting of millicharged magnetic monopoles from a dark U(1) sector with kinetic mixing to the Standard Model, deriving constraints on its parameters from dark matter self-interactions and the survival of galactic magnetic fields via the Parker effect across three distinct phenomenological scenarios.
This paper establishes a correspondence between the generalized Schur indices of 4d and superconformal field theories and the eigenfunctions of non-relativistic integrable models, such as the elliptic Ruijsenaars-Schneider and Inozemtsev systems, thereby deriving new mathematical identities and extending these relationships to various classes of SCFTs.
This paper demonstrates that the trapped interiors of black holes provide an exact, time-dependent framework for the classical double copy, proving that regular solutions like the Bardeen black hole yield finite single-copy gauge fields that satisfy standard energy conditions even when the corresponding gravitational core violates them.
