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 a novel effective Lagrangian for low-energy Yang-Mills theory that incorporates spontaneous BRST and anti-BRST symmetry breaking via a Fujikawa model, thereby generating effective gluon and ghost masses and reproducing the Curci-Ferrari model as a special case while maintaining an underlying nilpotent extended-BRST symmetry.
This paper applies the brick wall model to de Sitter horizons, demonstrating that while the superposition of independent near-horizon sectors in Schwarzschild-de Sitter space suppresses strict level repulsion, spectral form factors and Krylov complexity still robustly reveal the underlying chaotic dynamics of the system.
This paper presents a lattice field theory analysis of the 3D chiral Heisenberg model using domain wall fermions and Rational Hybrid Monte Carlo simulations to locate the SU(2) to U(1) phase transition, yielding critical exponents that align more closely with 3D covariant field theory estimates than previous (2+1)D results.
These lecture notes introduce the Dressing Field Method as a systematic framework for extracting gauge- and diffeomorphism-invariant physical observables in general-relativistic gauge field theory, illustrated through diverse applications ranging from Chern-Simons theory and electromagnetism to General Relativity.
This paper investigates Jackiw-Teitelboim gravity in two-dimensional de Sitter space by deriving a conditional density matrix from exact Wheeler-DeWitt solutions, revealing that the ground state is a mixed state rather than a pure Hartle-Hawking state and predicting a flat probability distribution for the universe's size.
This paper analyzes the all-orders asymptotics of the partition function for counting gauge-invariant functions of matrices, revealing a "small-cycle dominance" combinatorial structure and establishing that the asymptotic expansion becomes convergent for (or for the fermionic case), thereby allowing the complete reconstruction of the theory from its high-energy limit in these critical dimensions.
This paper demonstrates that the Higgs branches of 5d $Sp(k)$ theories with flavors are algebraic integrable systems described by a pair of pure spinor instantons, where the infinite coupling limit corresponds to an instanton alignment that induces non-vanishing magnetization and mass acquisition.
This paper investigates two distinct single-field brane inflation scenarios—radial and angular—within a warped deformed conifold geometry, where moduli stabilization via D7-brane Kuperstein embeddings generates the inflaton potentials, demonstrating that embedding these models in the warm inflation paradigm with dissipation enables them to satisfy current observational constraints from Planck and ACT, whereas their cold inflation counterparts fail.
This paper demonstrates that superradiant instability in Kerr primordial black holes generally suppresses the production of dark radiation from Hawking-emitted gravitons by extracting angular momentum, thereby necessitating a revision of existing constraints on primordial black hole mass and spin in the presence of beyond-the-Standard-Model bosons.
The paper explores how applying a stochastic approach to supersymmetric theories offers novel methods for characterizing anomalies associated with the breaking of supersymmetry.
