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 proposes an efficient framework for analyzing quantum field theories by combining a Daubechies wavelet basis with Similarity Renormalization Group flow equations to systematically decouple degrees of freedom across scales, thereby enabling the extraction of low-energy spectra from reduced-resolution Hamiltonian blocks with significantly lower computational cost.
This paper argues that the AI revolution's true significance lies in fundamentally transforming how scientific knowledge is carried and shared, shifting the role of AI from a mere efficiency tool to a structural collaborator that reshapes the entire research lifecycle while emphasizing the continued necessity of human diversity and learning for original discovery.
This paper establishes the ODE/IM correspondence between the linear problem of the supersymmetric affine Toda field equation for the twisted affine Lie superalgebra and 2d superconformal field theories by deriving WKB periods up to tenth order and verifying their agreement with the eigenvalues of local integrals of motion in the Neveu-Schwarz sector up to sixth order.
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 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 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 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.
This paper introduces a novel Kontorovich-Lebedev-Fourier frequency-momentum space for de Sitter correlators derived from the decomposition of spacetime isometry group representations, which simplifies perturbative computations by transforming propagators into rational functions and recasting loop integrals as orthogonality relations among group-theoretical coefficients.
This paper demonstrates that the Aretakis instability weakens as the degree of horizon degeneracy increases, leading to the proposal of a new black hole geometry with an infinitely degenerate horizon that is stable and could serve as a final "graveyard" state for extremal black holes.
