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.

This paper establishes a geometric framework for the BV-BRST quantization of 2-form gauge fields by utilizing Lie 2-algebroids and exact Courant algebroids derived from gerbe data, thereby naturally encoding the field-ghost tower and providing a setting for anomaly descent in 1-form symmetries.
This paper establishes a construction of supersymmetric vertex algebras from supersymmetric factorization algebras on super Riemann surfaces, demonstrating how the holomorphic sigma model in the BV formalism yields the chiral de Rham complex and its higher supersymmetric enhancements for Ricci-flat Kähler and hyperkähler targets.
This paper demonstrates that deconfined quantum critical points involving lattice symmetries can be reinterpreted as Landau-type transitions within a crystalline categorical framework, where gauging anomalous onsite symmetries generates noninvertible translation symmetries that distinguish between competing orders through their unique -symbols rather than just their fusion rules.
These lecture notes, delivered at the Universidad de Buenos Aires in 2026, provide a self-contained introduction to the off-shell double copy program for graduate students, covering fundamental gauge and gravitational theories and concluding with modern T-duality-invariant reinterpretations.
This paper improves the calculation of bulk viscosity in binary mixtures by deriving a second-order Chapman-Enskog result that captures essential physical features missed by first-order approximations and demonstrates significantly better agreement with Green-Kubo benchmarks.
This paper establishes a non-perturbative light-front framework to define and compute spin-orbit correlation distributions in charmonium and mesons via the parity-odd energy-momentum tensor, revealing that these observables provide rich, non-trivial insights into partonic dynamics even in systems with zero total angular momentum.
This paper utilizes the cosmological bootstrap framework to establish criteria distinguishing when boundary terms in quasi-de Sitter spacetime yield non-vanishing contributions to cosmological correlators, applying these insights to systematically classify and extract boundary effects in both dS-invariant and boost-breaking massive-exchange scenarios.
Using the Chapman-Enskog method within kinetic theory, this paper derives first- and second-order dissipative relativistic hydrodynamic equations for a multi-component quark-gluon plasma with baryon, electric, and strangeness charges, explicitly calculating the temperature and chemical potential dependence of the resulting diffusion matrix elements and their ratio to shear viscosity.
This paper presents a comprehensive study of anomalous quartic gauge couplings in same-sign boson scattering at the LHC within the SM Effective Field Theory framework, demonstrating that combining angular asymmetries derived from polarization and spin correlations with conventional kinematic observables yields improved constraints on Wilson coefficients while ensuring unitarity safety.
This paper proposes a mechanism where a direct inflaton-gluon coupling dynamically raises the QCD confinement scale during inflation to suppress axion isocurvature perturbations while allowing for later axion dark matter production, embedding this scenario in -attractor models to derive constraints on reheating and supersymmetry breaking scales.
