Using Embedding Theorems to Account for the Extreme Properties of Traversable Wormholes

2022-06-19T00:58:24+00:00

Embedding theorems, which have a long history in the general theory of relativity, are used in this paper to
account for two of the more troubling aspects of Morris-Thorne wormholes, (1) the origin of exotic matter
and the amount needed to sustain a wormhole, and (2) the enormous radial tension that is characteristic of
wormholes with moderately-sized throats. Attributing the latter to exotic matter ignores the fact that exotic
matter was introduced for a completely different reason and is usually present in only small quantities.

Higgs Portal Vector Dark Matter Interpretation: Review of Effective Field Theory Approach and Ultraviolet Complete Models

2022-04-19T20:13:35+00:00

A review of the Higgs portal-vector dark matter interpretation of the spin-independent dark-matter nucleon
elastic scattering cross section is presented, where the invisible Higgs decay width measured at the
LHC is used. Effective Field Theory and ultraviolet complete models are discussed. LHC interpretations
show only the scalar and Majorana dark-matter scenarios; we propose to include interpretation for vector
dark matter in the EFT and UV completions theoretical framework. In addition, our studies suggest an
extension of the LHC dark matter interpretations to the sub-GeV regime.

A Recipe for Conformal Blocks

2022-06-12T20:47:27+00:00

We describe a prescription for constructing conformal blocks in conformal field theories in any space-time dimension with arbitrary quantum numbers. Our procedure reduces the calculation of conformal blocks to constructing certain group theoretic structures that depend on the quantum numbers of primary operators. These structures project into irreducible Lorentz representations. Once the Lorentz quantum numbers are accounted for there are no further calculations left to do. We compute a multivariable generalization of the Exton function. This generalized Exton function, together with the group theoretic structures, can be used to construct conformal blocks for four-point as well as higher-point correlation functions.
