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 derives an analytic bound on axion mass and decay constant parameters in thawing quintessence models, demonstrating that when combined with observational data from DESI and supernovae alongside quantum gravity constraints, these bounds exclude vast regions of parameter space and push axion masses to be significantly larger than the Hubble scale, thereby challenging basic axion quintessence scenarios.
This paper proposes a covariant, gauge-independent framework for constructing foliation-based scalar-tensor theories with operators up to four derivatives that extend beyond DHOST and U-DHOST models, ultimately demonstrating that the theory propagates three physical degrees of freedom.
This paper explores the features of non-relativistic supersymmetric field theories from both Galilean and Carrollian perspectives, aiming to provide insights useful for constructing electric and magnetic non-relativistic theories derived from relativistic parents.
This paper presents a general prescription for spurion analysis that systematically tracks coupling constants in particle scattering processes governed by commutative non-invertible fusion algebras, unifying previous approaches and supporting the view that such non-invertible selection rules can be described by lifted Abelian groups with explicit breaking terms.
This paper investigates the production of light dark radiation particles (such as dark Higgs scalars, dark photons, right-handed neutrinos, and axion-like particles) via gravity-mediated interactions in the early universe, deriving constraints on the reheating temperature and equation of state from Planck 2018 CMB data and identifying future experimental prospects for probing these scenarios.
This paper investigates the fermionic Casimir effect for a Dirac field under MIT bag boundary conditions in the presence of CPT-odd Lorentz-violating background, demonstrating that while components parallel to the confining plates do not affect the renormalized energy, the normal component (both timelike and spacelike) induces a genuine correction that can be unified under a single effective spectral parameter.
This paper investigates a model of 3d gravity relevant to open CFT sectors by demonstrating that open Virasoro TQFT computes gravitational path integrals with specific boundary conditions and naturally derives the relationship between Conformal Turaev-Viro theory and diagonal Virasoro TQFT through open-closed duality.
This paper investigates whether higher-derivative terms in projectable Hořava gravity can stabilize its infrared instability by evolving into static, inhomogeneous solutions, but concludes that no such static endpoints exist, thereby reinforcing the necessity of time-dependent mechanisms like cosmic expansion to conceal the instability.
This paper establishes a framework for constructing worldvolume gauge theories on D2-branes probing non-toric compound Du Val Calabi-Yau threefolds by encoding their geometry as ADE surface fibrations in a Higgs field, which induces deformations via monopole superpotentials that, through 3d mirror symmetry, reproduce the mathematical quiver-collapsing mechanism.
This paper computes the quantum radiation emitted by relativistic single-electron wavepackets, demonstrating that while radiation vanishes for electrons at rest, uniformly accelerated electrons exhibit secularly growing power with a classical interpretation, and that proposed experimental signatures of the Unruh effect in specific "blind spots" are dominated by transverse deviation correlators rather than the Unruh effect itself.
