Characterization of the Response of Superheated Droplet (Bubble) Detectors
The PICASSO Collaboration, M. Barnabe-Heider, E. Behnke +19
The PICASSO project is a cold dark matter (CDM) search experiment relying on the superheated droplet technique. The detectors use superheated freon liquid droplets (active material…
Tau Neutrinos from Astrophysical and Cosmological Sources
Jane H. MacGibbon, Ubi F. Wichoski, Bryan R. Webber
Previous work on the neutrino spectra from high energy sources has not included the tau neutrinos directly produced by the decays in the source. Here we consider the tau neutrino c…
High Energy Fluxes from a Non-Scaling Cosmic String Network
U. F. Wichoski, R. H. Brandenberger, J. H. MacGibbon
Topological defects, particularly cosmic strings, can provide a mechanism to produce particles with energies of the order 10^21 eV and higher. Here, we report on order of magnitude…
On a Theory for Nonminimal Gravitational-Electromagnetic Coupling Consistent with Observational Data
R. Opher, U. F. Wichoski
The idea that the seed primordial magnetic fields can be explained by the nonminimal coupling between gravitational and electromagnetic fields is discussed. The predicted values of…
