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 Weak Gravity Conjecture via Gravitational Lensing, Black Hole Shadows, and Barrow Thermodynamics in F(R)-Euler-Heisenberg (A)dS Black Holes

This paper investigates the interplay between the Weak Gravity Conjecture and the Weak Cosmic Censorship Conjecture in F(R)F(R)-Euler-Heisenberg (A)dS black holes by demonstrating their thermodynamic compatibility through Barrow entropy, confirming the restoration of photon spheres via Euler-Heisenberg coupling, and analyzing observational signatures including gravitational lensing and black hole shadows.

Spatially inhomogeneous confinement-deconfinement phase transition in rotating QGP

Using first-principles lattice simulations, this paper reveals a novel spatially inhomogeneous phase in rotating gluon plasma where confining and deconfining regions coexist in thermal equilibrium, with the deconfined phase localized near the rotation axis and the confined phase at the periphery, a structure explained by action anisotropy in the curved co-rotating background rather than the standard Tolman-Ehrenfest law.

Universal and non-universal finite-volume effects in the vicinity of chiral phase transition in (2+1)-flavor QCD

This paper presents a finite-size scaling analysis of the chiral order parameter in (2+1)-flavor QCD using HISQ lattice data, demonstrating that infinite-volume extrapolated results align with expected O(2)O(2) scaling behavior while quantifying finite-size deviations to improve the precision of chiral phase transition temperature determinations.

Symmetric Mass Generation via Multicriticality in a 3D Lattice Gross-Neveu Model

Using large-scale Monte Carlo simulations, this study demonstrates that a 3D lattice Gross-Neveu model with two four-fermion interactions exhibits a multicritical point where the direct transition to a symmetric massive phase splits into two successive transitions (Gross-Neveu and XY universality classes) separated by a symmetry-broken phase, thereby unifying conventional and unconventional fermion mass generation mechanisms.

Matrix Correlators as Discrete Volumes of Moduli Space I: Recursion Relations, the BMN-limit and DSSYK

This paper demonstrates that specific correlators in generic one-matrix models define discrete volumes of Riemann surface moduli spaces obeying a discrete Mirzakhani-like recursion, which continuously recovers Kontsevich volumes in a BMN-like limit and yields a discrete qq-analog of Weil--Petersson volumes for DSSYK, thereby confirming a conjecture by K. Okuyama.

Direction-of-arrival estimation of a gravitational wave by correlations between quadrupole moments of pulsar timings

This paper proposes a method to estimate the direction of arrival of gravitational waves from isolated sources, such as supermassive black hole binaries, by analyzing the rank-2 traceless correlation matrix of quadrupole moments in pulsar timing data, demonstrating its potential for high angular resolution with future observatories like the Square Kilometer Array.

Exact Spinning Morris-Thorne Wormhole: Causal Structure, Shadows, and Multipole Moments

This paper presents an exact, analytically solvable spinning generalization of the Morris-Thorne traversable wormhole supported by anisotropic fluid, demonstrating its stable causal structure despite ergoregions, characterizing its distinctively smaller optical shadows compared to Kerr black holes, and identifying unique multipole moments that encode the throat scale in a massless, spinning configuration.
