Abstract

This is an exciting time for folks who are looking at neutrino cross sections, and the especially important quasielastic interaction. We are able to inspect several recent results from K2K and MiniBooNE and are looking forward to a couple more high statistics measurements of neutrino and anti-neutrino interactions. There is additional interest because of the need for this cross section information for current and upcoming neutrino oscillation experiments. This paper is a brief review of our current understanding and some puzzles when we compare the recent results with past measurements. I articulate some of the short term challenges facing experimentalists, neutrino event generators, and theoretical work on the quasielastic interaction.
