Status and Prospects of Long Baseline ν Oscillation Experiments

We will start with a brief overview of neutrino oscillation physics with emphasis on the remaining unanswered questions. Next we will discuss results and status of long baseline accelerator neutrino oscillation experiments that are in a mature data taking mode, have just started or are about to start data taking. Then, we will present the next generation of long baseline experiments with a primary goal to search for the yet to be measured third neutrino mixing angle. Finally we will introduce the plans for future long baseline accelerator neutrino oscillation experiments of which the primary goals are the search for CP violation in the neutrino sector, and the determination of the neutrino mass hierarchy. We will focus on experiments utilizing powerful (0.7 4.0 MW) neutrino beams, either existing or in the design phase.
