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 the shadow, strong-field lensing, and emission properties of static, spherically symmetric dilatonic black holes, demonstrating that increasing charge and dilatonic coupling reduces the shadow size and using these findings to constrain model parameters against observational data from M87* and SgrA*.
This paper demonstrates that a pre-geometric gravity framework based on a Yang–Mills-like gauge formulation with spontaneous symmetry breaking can consistently generate the effective metric and classical dynamics underlying the Geometric Trinity of Gravity, thereby unifying General Relativity, Teleparallel Gravity, and Symmetric Teleparallel Gravity as different manifestations of a single pre-geometric origin.
This paper presents a first direct regularized construction of the unprojected sectors of the Type IIB Superstring torus vacuum by developing sector-resolved modular integrals using an -prescription and -regularization framework, which is subsequently cross-checked via Lorentzian-inversion reconstruction.
This paper demonstrates that semiclassical entanglement entropy in a driven 2D CFT encodes its dynamical phases and, through a holographic dual calculation of backreacted geometry, provides a nontrivial verification of the Faulkner-Lewkowycz-Maldacena conjecture at the first quantum correction order.
This paper proposes a classical Hamiltonian formalism for plasmon bremsstrahlung in a hot quark-gluon plasma by generalizing the Lie-Poisson bracket to include non-Abelian color charges and deriving a self-consistent system of kinetic equations to describe the time evolution of plasmon number densities and hard particle color charges.
This paper investigates the conformal block decomposition of Witten diagrams for holographic defects by employing the split representation of AdS propagators to derive explicit OPE coefficients and recursion relations for tree-level diagrams, as well as closed-form expressions for defect-to-bulk crossing kernels in specific dimensions.
This study utilizes the Dynamical QuasiParticle Model and Parton--Hadron--String Dynamics transport approach to demonstrate that thermal QGP dilepton radiation becomes a dominant signal over correlated charm decays in central heavy-ion collisions at energies below 25–30 GeV, highlighting the potential of RHIC-BES and FAIR experiments to directly observe QGP electromagnetic radiation and probe the QCD phase structure.
This paper classifies 4-dimensional gravitational theories with integrability properties analogous to quasi-topological gravity for a specific set of symmetric metrics, demonstrating that only theories yielding third-order equations can be analytic in the Riemann tensor and constructing unique, regular static black hole solutions with first-order field equations from infinite towers of high-energy curvature corrections.
By combining Bayesian spline reconstruction with exhaustive symbolic regression on cosmological data within the VCDM framework, the authors identify a simple, one-parameter phantom-crossing dark energy model () that fits observations as well as standard two-parameter models while offering a more predictive, dynamically deformed alternative to the cosmological constant.
This paper reviews how one-loop corrections from matter fields during de Sitter inflation differentially affect gravitational wave mode functions, showing that while conformally coupled matter yields only logarithmic enhancements, massless minimally coupled scalars induce a significant shift in the real part of the mode function that can be interpreted as a modification of the inflationary Hubble parameter.
