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 cosmological implications of the "slingshot effect," a phenomenon where sources crossing domain walls generate confined strings, potentially sourcing gravitational waves, dark matter via Kaluza-Klein gravitons, and primordial black holes across observationally relevant mass ranges.
This paper presents a globally consistent Type IIA string theory framework on a orientifold that simultaneously addresses the strong CP problem via a four-form flux mechanism and predicts a multi-component dark matter scenario consisting of axions and neutralinos with computed relic abundances and observational signatures.
This paper advances the M-theoretic Emergence Proposal by demonstrating that the regularization used to derive classical cubic terms from quantum effects in 4D compactifications is equivalent in both complex structure and Kähler moduli spaces, and by extending this framework to account for linear terms in the one-loop prepotential .
This paper reviews fractional Kaehler potentials that, when combined with chaotic inflationary potentials in a non-linear sigma model, establish a class of -inflationary attractors compatible with ACT DR6 data and potentially observable tensor-to-scalar ratios, while also demonstrating their realization within supergravity via shift-symmetric Kähler potentials and monomial superpotentials.
This paper constructs an unfolded system for a free massless hypermultiplet that naturally generates the standard harmonic superspace formulation via vielbeinization and demonstrates the approach's background universality by systematically deriving formulations across harmonic, N=2, N=1, and component Minkowski superspaces.
This paper investigates the Tsallis holographic dark energy model under power law ansatz across viscous, non-viscous, and Chaplygin gas scenarios, analyzing their stability and phantom divide crossing to conclude that the Chaplygin gas scenario offers superior insights into stability issues.
This paper demonstrates that certain holographic dark energy models can lead to a "long freeze" scenario where the universe asymptotically approaches a static state with vanishing energy density, a behavior that can persist after an extended period of exponential expansion but is generally disrupted by the presence of nonrelativistic matter.
This paper presents a fully covariant toy model where a closed FLRW spacetime emerges as a 4-brane within a flat five-dimensional scalar field space, driven by a string-like potential without requiring explicit curvature terms in the action.
This paper comprehensively analyzes late-time cosmic scenarios, particularly rips, within a holographic dark energy framework using both primitive and generalized Nojiri-Odintsov cutoffs, while evaluating the validity of thermodynamic laws and energy conditions to demonstrate that consistent alternatives to the Big Rip are unattainable with simpler cutoffs but possible with the generalized approach.
This study demonstrates that the non-relativistic transverse velocity of an Unruh-DeWitt detector can slightly mitigate information degradation caused by the Unruh effect in accelerated quantum systems, while ultra-relativistic velocities effectively suppress the effect entirely.
