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 resolves the obstruction to partial-wave unitarity bounds in theories with massless particles by developing a modified perturbation theory that incorporates off-shell Coulomb modes, thereby rendering partial-wave amplitudes well-defined, renormalization scale independent, and free of spurious infrared regulator dependence.
This paper proposes a systematic top-down approach using cavity-based effective descriptions to derive observable gravitational wave signatures, particularly phase shifts, from modified black hole dynamics motivated by quantum consistency or new physics.
This paper constructs the generating function for the single-centered black hole index in general CHL models by subtracting the two-centered black hole contribution, derived via bound state metamorphosis, from the quarter BPS dyon index described by a meromorphic Siegel modular form, while proving convergence for the cases and .
This paper proposes a variational framework that treats reheating as a constrained optimization problem to identify equation-of-state histories that extremize specific cosmological observables, demonstrating that different signals like gravitational waves and primordial black holes select distinct regions of post-inflationary expansion histories without relying on microscopic models.
This paper presents four distinct D quantum models that realize the Yang-Lee phase transition under -symmetric deformation, demonstrating through analytical and numerical methods that their critical points are universally described by a massless bosonic field with an interaction and exhibit scaling dimensions consistent with exact two-dimensional results.
This paper constrains the mass of microscopic black holes produced at the LHC with TeV within the ADD model, demonstrating that higher energy loss during formation (parameterized by ) and varying numbers of extra dimensions significantly reduce the exclusion limits on the black hole mass for different reduced Planck scales.
This paper constructs and analyzes static monopole and monopole-critical-bubble configurations in the Coleman-Weinberg model to demonstrate how radiative symmetry breaking leads to metastable monopoles that lose stability via a saddle-point transition at a critical rescaled scalar mass of .
This paper proposes and numerically validates an explicit analytic formula for the leading ultraviolet asymptotic term of finite-volume vertex operator expectation values in the sine-Gordon model, derived from the kink nonlinear integral equation and shown to agree with complex Liouville conformal field theory predictions to high precision.
This paper proposes a novel cosmological model where dynamical dark energy arises from the non-perturbative topological structure of the QCD vacuum without introducing new fields, demonstrating that this physically motivated scenario fits current observational data as well as standard models while naturally predicting phantom-crossing behavior without theoretical instabilities.
This paper investigates the canonical quantization of Brane-Skyrmions in braneworld scenarios by deriving a perturbative Hamiltonian for their collective coordinates and employing Physics-Informed Neural Networks to determine energy-minimizing soliton profiles that incorporate spin backreaction, ultimately exploring the framework's potential for describing hadronic spectra.
