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 establishes a comprehensive, model-independent framework for thermal gauge theories with arbitrary temperature, chemical potentials, and angular momentum by developing path-integral methods to derive generalized KMS conditions and thermal propagators, demonstrating that while these thermodynamic parameters modify propagators, they leave interaction vertices unaltered in perturbation theory.
This paper reconstructs the effective potential and Gauss-Bonnet coupling function in Einstein-Gauss-Bonnet gravity using the scalar spectral index and tensor-to-scalar ratio consistent with ACT data, demonstrating that these functions are not inversely proportional, contrary to previous assumptions.
The paper proposes a new "Derivative Portal Dark Matter" model where a massive mediator couples to the Standard Model via derivative interactions, allowing the theory to naturally satisfy relic density constraints while evading limits from direct detection, indirect detection, and collider searches.
This paper derives a localization formula for the regularized on-shell action of supersymmetric solutions in five-dimensional minimal gauged supergravity, expressing it in terms of toric data and the supersymmetric Killing vector, and demonstrates its application by reproducing the entropy function of rotating black holes in AdS using only topological information.
This paper proposes a gauged extension of the Standard Model that utilizes the type-III seesaw mechanism to generate neutrino masses while employing anomaly-canceling chiral fermions as dark matter candidates, with a comprehensive analysis of their phenomenological signatures across cosmology, direct/indirect detection, collider physics, and gravitational waves.
This paper extends the differential homotopy approach to second-order perturbation theory in higher-spin theory, deriving general star-multiplication formulae, clarifying its relation to shifted homotopy, and obtaining projectively-compact spin-local quadratic vertices in the one-form sector.
This paper demonstrates a remarkable convergence between Basis Light-Front Quantization and Dyson-Schwinger equations in predicting charmonium light-front wave functions and associated observables, thereby validating both Hamiltonian and Lagrangian approaches for studying non-perturbative QCD structure.
This paper proposes a new QCD thermal history scenario where a heavy axionlike particle with a mass of approximately 5 MeV induces a Coleman-Weinberg type chiral phase transition via supercooling, potentially leading to unique cosmological phenomena such as mini-inflation, nonperturbative reheating, and the production of gravitational waves and primordial black holes.
This paper derives analytical templates for primordial tensor power spectra in curved inflationary universes, revealing that spatial curvature induces characteristic large-scale features like low- cut-offs and oscillations which offer a potential discriminant for curvature in future CMB observations.
This paper investigates the cosmological thermodynamic implications of Geodetic Brane Gravity, demonstrating how its extra-dimensional contributions modify horizon entropy and temperature while analyzing the sensitivity of thermal equilibrium between the apparent horizon and the bulk to the equation-of-state parameter.
