Neutrino Experiments Light the Way to New Physics

The neutrino is the oddest breed of fundamental particle. Neutrinos seem to defy all precedents set by better understood varieties of particles, such as electrons and quarks.
Lightweight, shifty and exceedingly difficult to detect, neutrinos have been vexing experimentalists for decades.
Even today fundamental properties of neutrinos remain up for debate. Some of the key questions pertain to the origin of their meager masses, the nature of neutrino antimatter and the number of neutrino species in existence, not to mention their penchant for switching identities on the fly.
Uncovering the true nature of the neutrino may pave the way to a more unified theory of physics.
