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.

A Consistent Treatment of Final-State Interactions in NuWro Quasielastic Channel

This paper presents a unified framework within the NuWro Monte Carlo generator that consistently treats final-state interactions in quasielastic lepton-nucleus scattering by combining convolution-based inclusive calculations with an event-level cascade classification, significantly improving agreement with both inclusive electron-scattering data and exclusive MicroBooNE measurements.

Induced Multi-phase Inflation with Reheating: Leptogenesis and Dark Matter Production in Metric versus Palatini

This paper investigates non-minimally coupled scalar-induced multi-phase inflation in both metric and Palatini gravity, demonstrating that while both frameworks align with observational constraints on the spectral index, Palatini models predict a significantly lower tensor-to-scalar ratio and sub-Planckian field excursions, leading to distinct reheating dynamics that constrain the production of dark matter and the viability of non-thermal leptogenesis within a Type-I seesaw framework.
