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 derives cubic interactions and arbitrary-spin propagators for Chiral Higher Spin Gravity in covariant gauges, confirming their agreement with light-cone results and demonstrating that tree-level amplitudes vanish in its self-dual truncation via Berends–Giele recursion.
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 presents a formalism for semiclassical time evolution in quantum mechanics that utilizes various complex and real saddle points to accurately reproduce known results and analyze metastable state decay, with the ultimate goal of developing methods to compute decay rates in time-dependent quantum field theories.
This paper proposes that if neutron star mergers trigger a first-order quantum chromodynamics phase transition, the resulting bubble nucleation and dynamics would generate distinctive megahertz-range gravitational waves, offering a new observational window for future detectors.
This paper establishes a relationship between the Euler numbers of moduli spaces of stable pairs supported on singular space curves and those of Flag Hilbert schemes associated with plane curve singularities by utilizing pagoda flop transitions, thereby deriving explicit results for locally complete intersection singularities.
This review surveys universality in driven open quantum matter, employing a Lindblad-Keldysh field theory framework to discuss principles distinguishing equilibrium from nonequilibrium stationary states and categorizing universal phenomena into paradigmatic nonequilibrium realizations, novel nonequilibrium universality, and genuinely quantum nonequilibrium effects.
This paper re-evaluates Standard Model vacuum stability using high-order perturbations and precise parameters to show that improved measurements of the top mass and strong coupling could confirm stability at the level, while also exploring viable singlet scalar extensions that remain stable up to the Planck scale and predicting significant deviations in Higgs couplings testable at current and future colliders.
