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 using noninvertible fusion algebras to generate fermion mass textures via operator hierarchies, identifying the rank-8 algebra as the best fit for Yukawa matrices while concluding that no studied fusion algebra successfully reproduces both fermion masses and mixing angles simultaneously.
This paper proposes studying the Collins effect in photon-photon collisions producing back-to-back hadrons at future colliders like the FCC and LHC, predicting sizable azimuthal asymmetries of up to 10–15% that could significantly advance the understanding of quark fragmentation and distinguish between existing Collins function models.
This paper demonstrates that promoting global axial symmetry to a gauge redundancy via field reparametrisation eliminates irrelevant anomalies and yields a non-propagating pseudoscalar Lagrange multiplier, which can become an emergent propagating degree of freedom through a Higgs mechanism on topologically non-trivial spacetimes.
This paper proposes four versions of nonlinear higher-spin gauge theories compatible with de Sitter geometry in the presence of fermions, two of which feature a Lie superalgebra structure and two of which exhibit unitarity in the bosonic sector alongside pseudo-involutions suggesting (anti)unitarity linked to time reversal or spacetime doubling.
This paper establishes the fundamental limits and constructs optimal recovery strategies for quantum information encoded against uncertain coherent rotation noise by utilizing Krylov geometry and polynomial projections to characterize error correctability, leading to exact infidelity bounds and finite-dimensional recovery protocols under various calibration constraints.
This paper derives mass formulas and asymptotic state densities for string models with fixed endpoints or baryon junctions, demonstrating that these configurations share the same universal Hagedorn temperature as ordinary open strings, thereby providing a microscopic explanation for its phenomenological universality.
This paper presents a dynamical systems and Bayesian analysis of an axio-dilaton model in string compactifications, demonstrating that non-geodesic field trajectories driven by a specific kinetic coupling can produce accelerated expansion even with steep potentials, a scenario that is slightly favored over CDM by current cosmological data while constraining the potential slope and coupling parameters.
This paper extends an exact lattice bosonization framework to the double-scaled matrix model, demonstrating that the theory is described by a boson on a finite, non-uniform lattice with spacing dependent on the position and string coupling, which yields finite results for local observables like entanglement entropy and fermion density that diverge in the traditional collective variable approach.
This paper presents sewing representations for tree-level all-plus wavefunctions in four-dimensional de Sitter space, deriving explicit formulas for both Yang--Mills theory and Einstein gravity that utilize noncrossing polygon dissections and labelled sewing trees, respectively, while highlighting the absence of total-energy poles and the necessity of local boundary terms.
This paper investigates the quasinormal modes and quasibound states of a massive scalar field in a logarithmically deformed Reissner-Nordström black hole spacetime, employing multiple analytical and numerical methods to demonstrate how nonlinear electrodynamics and scalar mass influence mode damping, binding energy, and state orthogonality.
