-
A.
KamLAND experiment
chosen
The KamLAND experiment is a neutrino observatory in Japan that made landmark measurements of neutrino oscillations by detecting antineutrinos from distant nuclear reactors and the Earth’s interior.
-
B.
Baksan Neutrino Observatory
The Baksan Neutrino Observatory is a Russian underground research facility in the Caucasus Mountains dedicated to detecting neutrinos and studying rare subatomic processes in a low-background environment.
-
C.
Tokai to Kamioka
Tokai to Kamioka is a long-baseline neutrino oscillation experiment in Japan that studies how neutrinos change type as they travel from the J-PARC facility in Tokai to the Super-Kamiokande detector in Kamioka.
-
D.
Kamiokande experiment
The Kamiokande experiment was a pioneering Japanese neutrino observatory that provided key evidence for solar and atmospheric neutrinos, contributing to the discovery of neutrino oscillations.
-
E.
Sudbury Neutrino Observatory
The Sudbury Neutrino Observatory is a deep underground Canadian physics facility that made landmark measurements of solar neutrinos, providing key evidence for neutrino oscillations and mass.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
