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 presents a constituent two-gluon model for the lowest-lying glueball states in pure Yang-Mills theory, calibrated against lattice results, which reveals that the compact scalar glueball has a radius comparable to the instanton size while the extended tensor state is shaped by a centrifugal barrier, with the framework also supporting Regge behavior for excited states.
This paper constructs explicit planar Anti-de Sitter spacetimes with multiple NUT parameters by introducing axionic scalar fields or quadratic-curvature corrections, thereby overcoming vacuum field equation restrictions and enabling the study of holographic properties with multiple NUT charges alongside Kaluza-Klein multi-monopole configurations.
This paper proposes a novel experimental setup where a charged Weber bar inside a shielded cavity interacts with gravitational waves via a semi-classical analogue of the Gertsenshtein effect, causing the bar to emit detectable photons as a means of gravitational wave detection.
This paper introduces three key improvements to the orbifold lattice approach for simulating SU(2) gauge theories on quantum computers—specifically new simplified Hamiltonians, a more qubit-efficient encoding, and a modified Hamiltonian term that reduces scalar mass requirements—thereby significantly lowering circuit depth and qubit needs while validating the efficacy of non-compact variables through (2+1)D Monte Carlo benchmarks.
This paper proposes a Type I seesaw model with symmetry and soft-breaking terms at the electroweak scale that successfully explains light neutrino oscillation data, identifies the lightest right-handed neutrino as a dark matter candidate via freeze-in, and generates the baryon asymmetry through resonant leptogenesis using only a minimal set of parameters.
This paper establishes an explicit free-field construction of Recknagel's permutation branes in Gepner models by demonstrating that only permutation matrices yield boundary conditions consistent with the singular vector structure of unitary N=2 superconformal minimal models.
This paper introduces -opers and establishes a one-to-one correspondence between them and nondegenerate solutions of Bethe Ansatz equations, thereby realizing a DE/IM correspondence that links the spectra of quantum integrable models (associated with either or its Langlands dual) to classical geometric objects via the $QQ$-system.
This paper derives a novel constraint from Slavnov-Taylor identities that identifies a constant tadpole term as the dynamical source of the mass gap, thereby distinguishing a general confining QCD theory with a physical mass gap from conventional QCD while preserving perturbative renormalizability and asymptotic freedom.
This paper demonstrates that the double-scaled algebra generated by chord operators in the double-scaled SYK model is a Type II factor with a tracial empty state, thereby unifying finite effective temperature perspectives with de Sitter gravity insights while exploring connections to JT gravity, baby universes, and Brownian SYK through analytic solutions of the energy spectrum.
This paper confirms that non-supersymmetric extremal black holes in N=8 string theory lack a sizeable ground state degeneracy by demonstrating that their D-brane description yields a unique ground state with non-zero energy, thereby implying the absence of truly extremal states.
