Search for v μ→ v τ Oscillations Motivation and Feasibility

Theoretical prejudices derived from solar-v matter oscillations and assumptions of neutrino mass hierarchies suggest, that v − oscillations are observable in laboratory with mass parameters of Δm2 = 10−3- 104eV2 . In particular v μ→v τ appearance searches at accelerators and ve→ vx disappearance experiments at reactors seem strongly motivated.
