Quest for the dynamics of $\nu_{mu} \to \nu_{tau}$ conversion
  We perform a quantitative analysis of the capability of K2K, MINOS, OPERA and a neutrino factory in a muon collider to discriminate the standard mass induced vacuum oscillation from the pure decoherence solution to the atmospheric neutrino problem and thereby contribute to unravel the dynamics that governs the observed $\nu_mu$ disappearence.
