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 resolves the DFSZ axion domain wall problem by demonstrating how the global structure of symmetry groups and non-invertible chiral symmetries enforce domain wall stability, suggesting that UV theories with small-instanton-induced symmetry breaking can naturally resolve the issue while producing distinct gravitational wave signatures.
This paper presents a systematic two-loop analysis of axion effective field theory within the BMHV scheme, demonstrating how evanescent operators arising from the non-anticommuting nature of violate naive Ward identities and deriving the necessary finite renormalization to restore consistency and correctly recover the axial anomaly.
This paper calculates half-maximal 4-point one-loop graviton amplitudes using string methods and infrared regularization via higher-point kinematics, employing analytically continued single-valued polylogarithms to obtain finite tensor structures and providing code to advance automation.
This paper demonstrates that deforming the spin-1 Babujian-Takhtajan chain with its third conserved charge, which acts as a dressed scalar-chirality operator, induces a quantum phase transition into a gapless, chiral current-carrying state described by a conformal field theory, a phenomenon verified through thermodynamic Bethe ansatz and DMRG simulations.
This paper proposes an intrinsic worldsheet description of ultra-high energy string scattering using tensionless null strings with induced vacuum symmetries, demonstrating that their constructed scattering amplitudes successfully reproduce the high-energy limits of standard string theory, including the Gross-Mende and Regge regimes, while revealing a fundamental blurring between open and closed strings and introducing new vertex operators unique to the zero-tension limit.
This paper demonstrates that the mathematical equations governing the masses of glueballs in the holographic QCD hardwall model are identical to those describing the vibrations of a classical circular drumhead, thereby providing a compelling motivation for undergraduate students to study drumhead dynamics as a gateway to understanding advanced particle physics.
This paper presents lattice evidence supporting the gauge-gravity correspondence in 3D maximally supersymmetric Yang-Mills theory by demonstrating that the spatial deconfinement transition temperatures for colors follow the holographic prediction .
This paper investigates the conjecture that non-unitary conformal minimal models arise from complex scalar field theories by testing long-range deformations, finding inconsistencies for but confirming that the long-range Lee-Yang model () behaves analogously to the long-range Ising model.
This paper investigates the late-time asymptotic behavior and attractor structure of spin density in minimal causal spin hydrodynamics under Gubser flow, demonstrating that in specific regimes, spin density decays as a hydrodynamic mode governed by late-time scaling laws similar to conventional thermodynamic variables.
This paper formulates the time-of-arrival problem for relativistic particles on a ring within Quantum Field Theory using the Quantum Temporal Probabilities method to derive POVMs, revealing how the ring's topology enables multi-pass detection, rotation induces Unruh-like noise, and entanglement generates non-classical temporal correlations, thereby realizing a quantum clock sensitive to local spacetime structure.
