Unitarity-Conserving Non-Minimally Coupled Inflation and the ACT Spectral Index
J. McDonald
The Atacama Cosmology Telescope (ACT) collaboration has reported a scalar spectral index . This is substantially larger than the classical prediction of…
Warm Dark Matter via Ultra-Violet Freeze-In: Reheating Temperature and Non-Thermal Distribution for Fermionic Higgs Portal Dark Matter
John McDonald
Warm dark matter (WDM) of order keV mass may be able to resolve the disagreement between structure formation in cold dark matter simulations and observations. The detailed properti…
Supergravity Modification of D-term Hybrid Inflation: Solving the Cosmic String and Spectral Index Problems via a Right-Handed Sneutrino
Chia-Min Lin, John McDonald
Supergravity corrections due to the energy density of a right-handed sneutrino can generate a negative mass squared for the inflaton, flattening the inflaton potential and reducing…
On the Effect of Asymmetric Strange Seas and Isospin-Violating Parton Distribution Functions on sin2thetaW Measured at NuTeV
NuTeV Collaboration, G. P. Zeller, K. S. McFarland
The NuTeV collaboration recently reported a value of sin2thetaW measured in neutrino-nucleon scattering that is 3 standard deviations above the standard model prediction. This resu…
F-Term Hybrid Inflation, the η-problem and Extra Dimensions
John McDonald
F-term hybrid inflation models in the context of supergravity generically have corrections to the inflaton mass squared of the order of H^{2} (the η-problem). In addition they have…
Search for heavy particles decaying into electron-positron pairs in p-pbar collisions
D0 Collaboration, V. M. Abazov
We present results of searches for technirho, techniomega, and Z' particles, using the decay channels technirho, techniomega, Z' -> e+e-. The search is based on 124.8 pb-1 of data…
