5 Mar 2012 | | Abstract: | GUT monopoles captured by the Sun’s gravitation are expected to catalyze
proton decays via the Callan-Rubakov process. In this scenario, protons, which
initially decay into pions, will ultimately produce
u_{e},
u_{mu} and
ar{
u}_{mu}. After undergoing neutrino oscillation, all neutrino species
appear when they arrive at the Earth, and can be detected by a 50,000 metric
ton water Cherenkov detector, Super-Kamiokande (SK). A search for low energy
neutrinos in the electron total energy range from 19 to 55 MeV was carried out
with SK and gives a monopole flux limit of F_M(sigma_0/1 mb) < 6.3 imes
10^{-24} (eta_M/10^{-3})^2 cm^{-2} s^{-1} sr^{-1} at 90% C.L., where eta_M
is the monopole velocity in units of the speed of light and sigma_0 is the
catalysis cross section at eta_M=1. The obtained limit is more than eight
orders of magnitude more stringent than the current best cosmic-ray
supermassive monopole flux limit, F_M < 1 imes 10^{-15} cm^{-2} s^{-1}
sr^{-1} for eta_M < 10^{-3} and also two orders of magnitude lower than the
result of the Kamiokande experiment, which used a similar detection method. | | Source: | arXiv, 1203.0940 | | Services: | Forum | Review | PDF | Favorites | |
