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 extends the analysis of the electromagnetic scoot effect to scattering processes involving dyons (particles with both electric and magnetic charges), demonstrating how the first-order post-Minkowskian boost-like angular momentum shift depends on the choice of spacetime slicing and comparing these results to the purely electric case within multiparticle state representations.
This paper presents the first complete computation of the renormalized stress-energy tensor for a massless scalar field inside a four-dimensional Schwarzschild black hole, revealing that near the spacelike singularity, the dominant quantum effect is a divergent vacuum-polarization stress that acts as a focusing source rather than a defocusing one, thereby failing to smooth the singularity within the fixed-background approximation.
This paper investigates how toral compactification and magnetic flux-induced quasi-periodicity affect the vacuum expectation values of the field squared and energy-momentum tensor for a charged scalar field in Fulling-Rindler spacetime, revealing topological contributions such as off-diagonal stress components and distinct asymptotic behaviors near the Rindler horizon that are applied to cylindrical and topological black holes.
This paper investigates the structure of neutron stars within the gravity framework by deriving modified Tolman-Oppenheimer-Volkoff equations, numerically solving them with realistic equations of state to determine mass-radius relations and maximum masses, and analyzing the behavior of the nonmetricity scalar to compare results with observational constraints.
This paper extends the calculation of multi-particle operator product expansions from pure Einstein gravity to supergravity, deriving ninety-five (anti)commutators for celestial soft currents and establishing nontrivial relations between celestial amplitudes through the analysis of gravitons, gravitinos, graviphotons, graviphotinos, and scalars.
This paper establishes a rigorous geometric correspondence between thermal partition functions of discrete-spectrum quantum systems and the Chern character of a "virtual physical sheaf" over spacetime, utilizing -equivariant Hamiltonian flows and the Grothendieck-Riemann-Roch formalism to unify spectral theory with characteristic class theory.
This paper examines the spectacular development of group theory over the twentieth century, highlighting its pivotal role in particle physics while also exploring its significant applications in statistical physics and theoretical biology.
This paper describes the extension of the variable flavor number scheme to three-loop order, which incorporates mass effects and heavy-quark parton distribution functions, validates this approach at large scales through renormalization group analysis, and provides numerical implementations of relevant Wilson coefficients.
This paper investigates the analytic structure of finite-temperature two-point functions in the large- SYK model by tracking complex-time singularities that persist to zero temperature, revealing how the leading singularity defines an effective temperature for operator complexity while the next-to-leading singularity suggests a connection to bouncing null geodesics in an emergent black hole geometry.
This paper introduces a Kontorovich-Lebedev-Fourier (KLF) space formalism that replaces nested time integrals with frequency integrals over rational propagators to compute tree-level cosmological correlators, demonstrating the method's efficacy through a complete analytical treatment of the double-exchange diagram expressed as a double series of hypergeometric functions.
