the face of overwhelmingly negative guidance from many theorists an experiment
called KamLAND, designed to search for neutrino mass, motivated by the
possibility of large flavor mixing might explain the “Solar Neutrino Problem” was
initiated in the late 90’s. “KamLAND”
began data taking in 2002 and the initial “long-baseline-reactor” phase of the
experiment was completed in late 2011.
To many peoples surprise KamLAND discovered what it was searching for,
and even more.
I will discuss some of the accomplishments of KamLAND which includes: the
most precise available determinations of particular neutrino parameters, a
proof of the large-mixing-angle solution to the Solar Neutrino Problem, the
most direct experimental evidence of the neutrino-oscillation effect, and recently,
a measurement of the geo-anti-neutrino flux with implications for the heat
budget of the Earth’s interior.
