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 quantitatively evaluates saddle-point expansion methods for testing self-dualities in 1+1 dimensional critical scalar theory, finding that while they accurately predict free energy, they deviate by approximately 25% from the peak location of the correlation length.
This paper investigates the Coulomb potential within a combined Podolsky and Carroll-Field-Jackiw electrodynamics framework, demonstrating that while the Podolsky term regularizes short-distance divergences, the Lorentz-violating CFJ background can reintroduce these divergences and significantly alter the interaction potential through both spatial anisotropy and timelike dispersion effects.
This paper establishes that global geometric relations among nodes in multi-node conifold degenerations constrain the realized extension classes to a specific subspace, unifying the perverse-sheaf, mixed-Hodge-module, and categorical descriptions of these degenerations with their resolution and smoothing counterparts.
This paper demonstrates that the previously proposed thermodynamic interpretation of scalar-tensor gravity, which attributes a non-zero temperature to departures from general relativity, is not frame-invariant, and instead establishes a frame-invariant formulation where the effective fluid is perfect with zero temperature, identifying a frame-invariant chemical potential as the true driver of deviations from general relativity.
By upgrading the weak-coupling expansion of thermal SYM thermodynamics to the exact coefficient, this study demonstrates that the constrained log-subtracted two-point Padé ensemble collapses to a single unique curve, thereby eliminating scan uncertainty while highlighting a persistent discrepancy with the Hermite-Padé approach and identifying the need to compute the unknown strong-coupling coefficient.
This paper forecasts that upcoming radio telescopes, specifically LOFAR2.0, FAST Core Array, and BINGO, will significantly enhance the ability to constrain the fraction of dark matter composed of Primordial Black Holes by detecting or ruling out lensed Fast Radio Bursts across various mass ranges.
This study estimates pulsar beaming fractions across radio, X-ray, and gamma-ray bands using TeV-selected pulsar wind nebulae and unidentified sources, revealing survey-dependent variations likely caused by selection effects and pulsar age differences, which can be reconciled within a unified framework employing a time-dependent opening angle.
This paper constructs two inequivalent noncommutative quantum field theories on -Minkowski space using the Batalin-Vilkovisky formalism, demonstrating that a braided -algebra approach yields standard logarithmic divergences without UV/IR mixing, while a classical -algebra approach exhibits a periodic form of UV/IR mixing characterized by non-analyticity on an infinite lattice of exceptional momenta.
This paper presents the first beyond-next-to-leading-order study of the process by developing a complete four-dimensional tensor decomposition, evaluating one-loop polarized amplitudes analytically to higher orders in the dimensional regulator, and establishing an efficient numerical framework for five-point Feynman integrals to enable future NNLO predictions for radiative return processes.
This paper demonstrates that energetic final-state radiation induces decoherence and significantly reduces the entanglement of fermion-antifermion pairs produced at colliders, with statistically significant experimental signals predicted for current datasets from production at the LHC and production at Belle 2.
