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 investigates holographic duals of codimension-2 supersymmetric defects in maximally supersymmetric Yang-Mills theories by constructing Type II supergravity solutions from branes wrapping spindle configurations, deriving a prescription for defect entanglement entropy that scales with the ambient free energy, and distinguishing these defect solutions from circle compactifications in the D5-brane case.
This paper argues against the conjecture that bulk local field algebras exist within causal diamonds at finite UV cutoffs, asserting instead that such a description only emerges in a double-scaled limit where the boundary cutoff and both approach infinity, thereby precluding any bulk field theory resolution of distances smaller than the AdS radius.
This paper demonstrates through a systematic holographic study that the oscillatory behavior of Krylov complexity, controlled by the confinement scale, serves as a universal signature of confinement and infrared reorganization in strongly coupled quantum field theories.
Motivated by trans-Planckian issues, this paper establishes the Hilbert space and quantum amplitudes for general multi-field inflation without relying on the sub-horizon limit by utilizing Dirac brackets to handle field mixings and constraints, thereby enabling estimates of higher-derivative corrections in terms of slow-roll parameters and cutoff scales for various inflationary models.
This paper proposes that the dynamical inverse seesaw mechanism, which explains light neutrino masses through a low-scale lepton number-violating term, can be probed via low-frequency stochastic gravitational waves detected by pulsar timing arrays, offering a unique window into parameter space with small active-sterile mixing that is inaccessible to conventional particle physics experiments.
This paper investigates how collider and non-collider probes can constrain the reheating temperature, dark matter mass, and interaction scale of a scenario where dark matter transitions from WIMP to FIMP production via p-wave suppressed interactions, demonstrating that collider experiments are uniquely powerful in constraining derivative operators that are weakly limited by astrophysical observations.
This paper investigates spontaneous breaking of non-invertible symmetries in lattice models, demonstrating that such phases are characterized by long-range correlations of local order parameters obeying generalized algebraic structures and can be dual to deconfined quantum critical points of invertible symmetries via generalized gauging, thereby providing a systematic framework for studying beyond-Landau phase transitions.
The paper introduces `dualGNN`, a compact and efficient autoregressive graph neural network that leverages signed circuits from oriented matroid theory to uniformly sample fine, regular triangulations of convex polytopes, enabling the unprecedented generation of Calabi-Yau threefolds at high Hodge numbers with significantly reduced computational resources compared to prior methods.
Using the functional renormalization group, this study demonstrates that in QCD-like theories, a $CP$-violating four-fermion interaction becomes relevant in the chirally broken phase while the running of the -parameter is strongly suppressed toward the infrared in the presence of finite quark mass, thereby clarifying how strong-$CP$ effects generated at high energies are transferred to low-energy physics.
This paper proposes a worldline formulation of higher-spin gravity in based on a twistor action and a double-line interpretation that enables the construction of covariant vertex operators, allowing the computation of correlation functions that reproduce those of free vector models while suggesting a deeper connection to string theory via a Poisson sigma model embedding.
