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 demonstrates that for composite quantum systems with commuting subsystems, the leading excess in both Krylov complexity and entropy is governed by the weighted variance of subsystem Lanczos coefficients, thereby establishing these metrics as complementary tools for characterizing dynamical heterogeneity and the emergence of collective dynamics.
Using the gravitational shockwave formalism, this paper computes the classical part of the five-point amplitude for graviton emission in the collision of two massless scalars within multi-Regge kinematics, decomposing the result into two- and three-particle reducible terms and verifying its consistency with the ultrarelativistic limit of massive amplitudes via the optical theorem.
This paper proposes that the sign of the modification in the in-jet charmed baryon-to-meson ratio () serves as a key discriminator between hadronization mechanisms, where color reconnection in p+p collisions enhances the ratio while coalescence in Pb+Pb collisions suppresses it, offering distinct predictions for future jet-tagged measurements.
This paper presents a procedure that adapts modern unitarity methods to efficiently compute the cut-constructible parts of Magnus amplitudes, which are defined as the matrix elements of the logarithm of the S-matrix, without relying on Feynman diagrams.
This thesis presents the first analytic computation of the impulse for classical black hole scattering up to the fifth Post-Minkowskian order using the worldline quantum field theory framework, revealing that the solution involves periods over Calabi-Yau manifolds.
This paper constructs integrable 2d sigma models via 4d Chern-Simons theory to establish a correspondence with Hitchin systems, demonstrating that their quantized dynamics align with the Perelman operator and enabling the derivation of exact quantization conditions for the sausage model through 4d gauge theory and 2d CFT methods.
This paper investigates holographic duals of supersymmetry-breaking conformal surface defects in SYM theory, constructing new D5- and D7-brane embeddings that describe defect renormalization group flows and demonstrating that these flows satisfy the -theorem.
This paper introduces a torsional (0,2) linear sigma model that connects a five-dimensional heterotic flux vacuum in its large radius phase to a stringy asymmetric orbifold regime, while also developing general tools for constructing such heterotic vacua.
This thesis investigates the perturbative dynamics and observational signatures of compact objects within quadratic gravity and asymptotic safety, revealing unique instabilities and horizonless mimics in Einstein-Weyl gravity while demonstrating how quantum corrections in asymptotically safe gravity lead to regular black holes with modified evaporation rates that could impact dark matter models.
This paper establishes a complete formulation of maximal Cartan-gauged seven-dimensional supergravity and derives the full set of timelike supersymmetric geometries, revealing distinct structural behaviors based on flux activation and providing a systematic classification and toolbox for constructing BPS solutions and exploring holographic applications.
