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.

Testing the AdS/CFT Correspondence Through Thermodynamic Geometry of Nonlinear Electrodynamics AdS Black Holes with Generalized Entropies

This paper investigates the thermodynamic geometry and phase transitions of Anti-de Sitter black holes in ModMax, nonlinear electrodynamics, and Euler-Heisenberg theories under standard, Rényi, and Kaniadakis entropy frameworks, demonstrating that singularities in the geometrothermodynamic curvature consistently identify critical points that are preserved in their holographic dual conformal field theories.

Probing the chiral and U(1)U(1) axial symmetry restoration via meson susceptibilities in holographic QCD

Using a soft-wall holographic QCD model calibrated to reproduce the physical pion mass and pseudocritical temperature, this study demonstrates that while chiral symmetry restoration is clearly signaled by the degeneracy of chiral partner meson screening masses near TpcT_{\rm pc}, the restoration of U(1)U(1) axial symmetry occurs at a distinctly higher temperature (T∼0.190T \sim 0.190 GeV), highlighting a qualitative limitation of the model in describing the U(1)U(1) axial anomaly compared to Lattice QCD.

On Radiative Fluxes and Coulombic Charges in the Balance Law for Black Hole Evaporation

This paper derives a semiclassical balance law for the Bondi mass in 3+1 dimensional black hole evaporation, demonstrating that the radiative energy flux receives a positive quantum correction dependent on the entanglement entropy of Hawking radiation, which differs from the standard Fulling-Davies formula and extends insights from 2d dilatonic models.

Radiative return meets GVMD

This paper improves the description of pion-photon interactions in the radiative return process e+e−→π+π−γe^+e^-\to \pi^+\pi^-\gamma by incorporating the pion form factor into Feynman rules at next-to-leading order, revealing percent-level effects in angular distributions near the pion form factor peak while demonstrating that total cross sections remain largely unaffected, with the new framework implemented in the Phokhara\texttt{Phokhara} generator and validated against KLOE measurements.

Negative Masses and Spatial Curvature: Alleviating Neutrino Mass Tensions in LambdaCDM and Extended Cosmologies

This paper demonstrates that incorporating spatial curvature and dynamical dark energy into cosmological models, while employing a symmetric extension to handle negative effective neutrino masses, significantly alleviates the tension between current cosmological upper bounds and the terrestrial lower limit on the sum of neutrino masses by reducing the statistical discrepancy from 2.59σ2.59\sigma to approximately 1.1σ1.1\sigma.

A search for super-imposed oscillations to the primordial power spectrum in Planck and SPT-3G 2018 data

This paper analyzes Planck and SPT-3G 2018 data to search for super-imposed oscillations in the primordial power spectrum, finding that combined datasets provide tighter constraints on oscillation amplitudes and reveal improved fits with significant statistical gains compared to individual datasets.

Parton Distribution Functions in the Schwinger model from Tensor Network States

This paper proposes and demonstrates a method using tensor network states within the Hamiltonian formalism to accurately compute parton distribution functions for the vector meson in the massive Schwinger model directly in Minkowski space, thereby overcoming the limitations of Euclidean lattice calculations and offering a pathway for quantum simulations.
