For neutrino oscillation experiments it is very important to model nuclear effects in neutrino interactions. In order to study these effects, new observables have been measured in pion-less production at the MINERvA experiment, including transverse kinematic imbalances and the initial-state momentum of the struck neutron.This poster will review the variables, summarize recent results and preview new high statistics measurements of these variables using new MINERvA data.These measurements will allow better modeling of the neutrino-interaction models and the technique can be applied in future experiments where the effects of the nucleus are large
