A High Sensitivity Search for ${\bar{\nu }}_e$'s from the Sun and Other Sources at KamLAND

KamLAND Collaboration

Data corresponding to a KamLAND detector exposure of 0.28 kton-year has been used to search for ${\bar{\nu }}_e$'s in the energy range 8.3 MeV $<$ E${}_{{\bar{\nu }}_e}$ $<$ 14.8 MeV. No candidate…
