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 scattering and confining properties, including bound states and resonances, of the one-dimensional Dirac equation with a general relativistic contact interaction supported on two symmetric points, utilizing a distributional method to analyze parity-symmetric configurations and their critical states.
This paper rigorously computes the annealed and quenched free energy limits of the Sachdev-Ye-Kitaev (SYK) model at high temperatures using a novel mathematical approach based on sparse random graph theory and a variant of the cavity method, confirming results previously derived heuristically by physics methods.
This paper introduces an analytic framework for gravitational lensing in hadronic media by modeling hadrons via a nonlinear sigma model coupled to Maxwell theory, demonstrating that photons acquire an effective mass and deviate from null geodesics, which allows for the derivation of a modified Raychaudhuri equation and the calculation of deflection angles without relying on phenomenological refractive index models.
This paper employs the multiscale loop vertex expansion to construct cumulants for the quartic tensor field theory known as the model, proving their analyticity and Borel summability up to a finite order.
This paper investigates a proposed one-parameter family of conformal boundary states in the compact free boson CFT at irrational radii, providing an explicit density of states formula while highlighting their pathologies, such as a divergent g-function and potential violations of the cluster condition.
This paper introduces a three-dimensional quantum field theory featuring an infinite-dimensional topological-holomorphic symmetry that generalizes Wess-Zumino-Witten chiral symmetry, demonstrating that its local operators form a raviolo vertex algebra to extend two-dimensional conformal field theory methods into three dimensions.
This paper utilizes Frobenius recursion relations to rigorously establish the growth and alternating sign behavior of rank-2 quasi-character coefficients in the intermediate energy regime, thereby providing a practical method to construct admissible partition functions for rational conformal field theories via the holomorphic modular bootstrap.
This paper theoretically extends the Lifshitz formula to demonstrate that the anomalous magnetic moment of Dirac fermions significantly enhances the fermionic Casimir energy under magnetic fields, particularly through the gapless behavior of the lowest Landau level, while providing quantitative estimates for electrons, muons, and constituent quarks.
Using Monte Carlo simulations on SU(3) gauge theory lattices, this study investigates topologically stable strings formed at domain wall junctions in the deconfined phase, revealing that their free energy is dominated by the walls and that thermal fluctuations near the transition point cause these structures to decay into confined-deconfined interfaces.
This contribution applies the string-Carroll expansion scheme to systematically analyze and classify the dynamics of closed bosonic strings in the spacetime background of a non-extremal BTZ black hole near the horizon, thereby revealing new features of their solution space.
