Unparticles: Interpretation and Cosmology
John McDonald
We discuss the physical interpretation of unparticles and review the constraints from cosmology. Unparticles may be understood in terms of confined states of a strongly-coupled sca…
Supersymmetric inflation and baryogenesis via Extra-Flat directions of the MSSM
John McDonald, Osamu Seto
One interpretation of proton stability is the existence of extra-flat directions of the MSSM, in particular and , where the operators lifting the poten…
RH Sneutrino Condensate CDM and the Baryon-to-Dark Matter Ratio
John McDonald
The similarity of the observed mass densities of baryons and cold dark matter may be a sign they have a related origin. The baryon-to-dark matter ratio can be understood in the MSS…
Supergravity and Two-Field Inflation Effects in Right-Handed Sneutrino-Modified D-term Inflation
Chia-Min Lin, John McDonald
We extend previous work on the minimal D-term inflation model modified by Right-Handed (RH) sneutrino fields to include additional inflaton-sector SUGRA corrections and two-field i…
Gauge Singlet Scalars as Cold Dark Matter
John McDonald
In light of recent interest in minimal extensions of the Standard Model and gauge singlet scalar cold dark matter, we provide an arXiv preprint of the paper, published as Phys.Rev.…
Spectral Index of Curvaton Perturbations in Flat Potential Inflation Models
John McDonald
This paper has been withdrawn. Comments regarding D-term inflation will be incorporated in a forthcoming article.
