The journey starts with the T2K (Tokai to Kamioka) long baseline neutrino oscillation experiment in Japan. The main topics addressed will be the measurement of the nm flux at the near detector with T2K's first data as well as a possible implementation of pion formation zone reweighting. Also, brief feasibility studies for the calibration of the near detector tracker's absolute momentum scale and the measurement of the neutral current single pion production cross-section in the p0 near detector will be shown. The second part of the talk will focus on LArIAT, a liquid argon time projection chamber that will be placed in a test-beam at Fermilab. The goals of the experiment and its online monitoring system will be presented.
