Calculated event rates for Axion Detection via Atomic and Nuclear Processes
John D. Vergados, Paraskevi C. Divari, Hiroyasu Ejiri
The possibility of detection of 5.5 MeV and 14.4 keV solar axions by observing axion-induced nuclear and atomic transitions is investigated. The presence of nuclear transitions bet…
Supernova neutrino scattering off Gadolinium odd isotopes in water Cherenkov detectors
Paraskevi C. Divari
In this work, the supernova neutrino(SN) charged-current interactions with Gd odd isotopes (A=155 and 157) are studied. We use measured spectra and the quasiparticle-phonon model (…
Supernova Neutrino Scattering off Gadolinium Even Isotopes in Water Cherenkov Detectors
Paraskevi C. Divari
Neutrinos in water can be detected thanks to several reactions. The most important one is the inverse beta decay . The detection of 2.2 MeV from n…
Heavy sterile neutrino in dark matter searches
Paraskevi C. Divari, John D. Vergados
Sterile neutrinos are possible dark matter candidates. We examine here possible detection mechanisms, assuming that the neutrino has a mass of about 50 keV and couples to the ordin…
Neutrino oscillations in the presence of super-light sterile neutrinos
P. C. Divari, J. D. Vergados
In this paper, we study the effect of conversion of super-light sterile neutrino (SLSN) to electron neutrino in matter like that of the Earth. In the Sun the resonance conversion b…
Renormalization of the Spin-dependent WIMP scattering off nuclei
P. C. Divari, J. D. Vergados
We study the amplitude for the spin-dependent WIMP scattering off nuclei by including the leading long-range two-body currents in the most important isovector contribution. We show…
