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 employs a path-integral formulation based on the geometric realization of combined deformations to derive explicit expressions for two- and three-point correlators in two-dimensional CFTs deformed by both and root-, demonstrating that the deformed two-point function can be represented as a weighted average of undeformed correlators over conformal dimensions.
This paper investigates the parameter space for a vanishing effective Majorana mass in a sterile neutrino framework, demonstrating that while cosmological bounds on the sum of neutrino masses constrain the sterile mixing angle and lightest active neutrino mass, the resulting cancellation mechanism renders the sterile mixing angle insensitive to the high-precision solar oscillation measurements expected from the JUNO experiment.
This paper investigates monodromy defects for non-invertible symmetries in Maxwell theory by utilizing a conformal mapping to to recover defect conformal primaries and characterize how Wilson/'t Hooft lines terminate on, decompose into, or exhibit topological Chern-Simons behavior near these defects.
This paper provides an updated overview of the symmetry-preserving Contact Interaction model, demonstrating its effectiveness in describing the mass spectra and elastic form factors of forty mesons and their diquark partners while evaluating its performance against recent literature and lattice QCD, and highlighting its potential for future applications in light of upcoming experimental data from FAIR, Jefferson Lab, and the Electron Ion Collider.
This paper presents a minimal, resource-efficient framework for digitally simulating SU() pure Yang-Mills theory in 3+1 dimensions by combining an orbifold lattice protocol with simplified Hamiltonians and SU(2) embedding techniques, while validating these analytical improvements through Monte Carlo benchmarks to support practical quantum simulation of non-Abelian gauge theories.
This paper establishes the existence and uniqueness of smooth, Ricci-flat, toric ALE and ALF gravitational instantons for every admissible rod structure and provides an elementary proof that any such toric self-dual instanton corresponds to a multi-Eguchi-Hanson or multi-Taub-NUT solution.
This paper investigates novel surface critical behavior in the three-dimensional Gross-Neveu-Yukawa model by deriving exact infrared solutions for interacting fermions, demonstrating how fermionic anomalies manifest in surface dynamics, and revealing emergent topological and geometric structures in defect coupling space that relate to a defect analogue of the CFT distance conjecture.
This paper corrects the subleading coefficient in the regular-center Frobenius expansion for static tidal perturbations of relativistic stars and extends the even-parity master equation to Schwarzschild-de Sitter backgrounds, demonstrating that while the corrected coefficient alters initial data, it does not affect the extracted Love number .
This paper derives a first-order stochastic framework from the Schwinger-Keldysh formalism that systematically incorporates metric perturbations to describe non-perturbative inflationary dynamics in ultra-slow-roll regimes, validating the approach through numerical simulations of Starobinsky and critical Higgs inflation models.
This paper introduces a primal bootstrap framework using finite-resolution sampling to derive improved projective bounds and new non-projective constraints on effective field theories with graviton poles, demonstrating that in five dimensions the EFT cutoff cannot exceed the Planck scale and revealing distinct extremal spectral structures characterized by quadratic Regge-like trajectories or sharp bands.
