Query: Review of Neutrino Oscllations Experiments   Several experiments have sought evidence for neutrino mass and mixing via the
phenomenon of neutrino flavor oscillations. In a three neutrino model, these
oscillations are described by three angles, two mass splittings, and one CP
violating phase. Experiments using neutrinos from the Sun, the atmosphere,
nuclear reactors, and particle accelerators have gathered considerable
information on these angles and splittings. Two of the three angles are known
to be large: $\theta_{12} \simeq 33^\circ$, $\theta_{23} \simeq 45^\circ$, and
an upper limit is known on the third, $\theta_{13}<10^\circ$. Likewise, the
mass splittings are known to fall in the range $\Delta m^2_{12} \simeq 8 \times
10^{-5}$ and $|\Delta m^2_{23}| \simeq 2.4 \times 10^{-3}$ eV$^2$. Several
questions remain: the sign of the 2--3 mass splitting, the size of the unknown
angle $\theta_{13}$, and the size of the CP violating phase are yet to be
measured. Also, a report of short-baseline $\bar{\nu}_e \to \bar{\nu}_mu$
oscillations has yet to be confirmed. These open questions are the target of an
experimental neutrino oscillation program currently underway. This report will
attempt to summarize the current state of neutrino oscillation measurements and
the future program in as succinct a manner as possible.
