We studied the influence of a slow classical noise on Landau-Zener transitions. We demonstrated that the slow colored noise characterized by correlation time much greater compared to Landau-Zener time can produce transition itself or can change substantially the Landau-Zener transition probabilities. Exact formulas for finite time probabilities are derived by solving equation of motion for the density matrix. Connections between the slow noise induced Landau-Zener theory and recent experiments on double quantum dots are discussed.
