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 systematically investigates kink solutions in two-component scalar field theories with quartic potentials using the Bogomolny formalism, demonstrating that generalized superpotentials yield new models featuring continuous families of composite kinks with nontrivial internal structures.
This paper proposes a generally covariant formulation of the operator product expansion in D-dimensional Euclidean conformal field theories by organizing the series in powers of geodesic distance and utilizing tangent vectors for tensor contractions, explicitly demonstrating that universal curvature terms, such as those involving the Schouten tensor, arise in the expansion and are essential for conformal perturbation theory on curved spaces.
This paper investigates the unitarity violation scale of a non-minimally coupled scalar field with quartic self-coupling by calculating six-point scattering amplitudes in both Jordan and Einstein frames, explicitly demonstrating their frame-independence and showing that the dominant contribution arises from the scalar potential.
This paper utilizes the unitary irreducible representations of the infinite-dimensional asymptotic symmetry groups of QED and gravity to encode universal infrared features of scattering processes and explores the construction of an infrared-finite -matrix by studying supermomentum eigenstates in contrast to the dressed-state approach.
This paper demonstrates that geometric observables, such as length, measured by different inertial observers in Minkowski spacetime do not generically Poisson commute, a finding that offers significant insights into the potential existence of a fundamental scale in quantum gravity.
This paper utilizes a covariant spinor moving frame quantization of type IIA and IIB superparticles to reveal a hidden $SU(8)$ symmetry in linearized supergravity, demonstrating that both theories can be described by identical analytic on-shell superfields and superamplitudes while highlighting specific challenges in extending this formalism to include D0-branes.
This paper argues that the formation of a Schwarzschild black hole from a non-singular configuration cannot occur as a continuous process, as the geometry inevitably develops a "Minkowski breaking" discontinuity and curvature singularities before the point source forms, implying that black hole emergence requires a noncontinuous, possibly quantized, framework.
This paper critiques a 2025 study by Ballardini et al. for incorrectly calculating third-order slow-roll corrections due to improper integration techniques, demonstrating through numerical Monte-Carlo methods that the original exact analytical results by Auclair and Ringeval remain valid.
This paper develops a fully field-theoretic effective description of photon condensation in a hadronic cavity by deriving analytic criteria for condensation and mapping the reduced dynamics to standard nonlinear quantum-optics Hamiltonians, thereby bridging finite-density hadronic physics with experimental cavity diagnostics.
This paper constructs a class of higher-dimensional asymptotically AdS black holes whose interiors exhibit bona fide chaotic BKL dynamics characterized by billiard-like motion in a -simplex, revealing new era structures for and a holographic thermal -function that tracks these epoch transitions.
