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 introduces a novel, manifestly Lorentz-invariant action for duality-symmetric gauge theories featuring a new -gauge symmetry, which unifies potential and flux descriptions, enables straightforward minimal coupling to matter and supersymmetrisation, and provides a proof of charge quantisation applicable to both the new and Sen's formalisms.
This paper establishes novel analytic results for Virasoro modular and fusion kernels at rational central charges, revealing that these kernels can be expressed as linear combinations of non-symmetric functions with square-root branch point singularities, thereby demonstrating the crossing symmetry and modular covariance of timelike Liouville theory and suggesting a semiclassical, one-loop exact behavior relevant to 2d CFT and 3d TQFT.
This paper presents a systematic re-examination of symmetry classifications in three-Higgs-doublet models, identifying limitations in previous approaches and expanding the known set of realisable symmetries by incorporating generalized GOOFy transformations to provide a clearer theoretical framework for model building.
This paper proposes a Z3-symmetric extension of the Lorentz group to describe quark color triplets as entangled Lee-Wick fields with complex conjugate masses, resulting in sixth-order dispersion relations that naturally enforce the asymptotic confinement of colored quarks.
This paper demonstrates that the background instability of quintessence models can be comprehensively understood through the lens of entropy by showing that a rapid increase in matter entropy, driven by the distance conjecture, violates the covariant entropy bound and implies the existence of a finite event horizon that conflicts with the trans-Planckian censorship bound, while also linking scale separation to the AdS distance conjecture.
This paper proposes that a matter-free, three-torus universe driven by Casimir energy can evolve from a Planck-scale origin to a present size consistent with cosmic microwave background anomalies, provided specific parameters regarding particle content, inflation, and reheating are met.
This paper revisits the variational principle for relativistic perfect fluids using a manifestly covariant differential forms formalism to clarify boundary conditions for timelike flows and demonstrates that extending this principle to null flows dynamically forces the enthalpy density to vanish, resulting in a stress-energy tensor composed of variable vacuum energy and null dust.
This paper resolves the long-standing inconsistency of charged massive spin-3/2 fields in Einstein-Maxwell backgrounds by demonstrating that gravitational coupling imposes a lower mass bound near the Planck scale, thereby validating fractionally charged supermassive gravitinos as viable dark matter candidates.
This paper establishes a geometric framework for non-supersymmetric effective gauge theories by constructing supersymmetric embeddings of dimension-six operators and utilizing vector bundles to systematically organize gauge operators under field redefinitions, thereby revealing an underlying complex geometry.
This paper provides a constructive derivation of the continuum height field theory for the two-dimensional classical dimer model on square and honeycomb lattices by starting from an exact Grassmann integral representation, taking the continuum limit to obtain massless Dirac fermions, and applying bosonization to map the system to a height model that fully describes its long-distance correlations and topological properties.
