MiniBooNE experiment: description and results

The primary goal of the MiniBooNE experiment is to test neutrino mass by searching for neutrino oscillations. The first MiniBooNE neutrino oscillation results published April of 2007 ruled out the simple two neutrino oscillation hypothesis of the LSND experiment. However, MiniBooNE unexpectedly observes a significant excess of electron-like events below a reconstructed neutrino energy of 475 MeV. An analysis of this low energy region for neutrino and anti neutrino modes will be presented. The MiniBooNE experiment also has collected an unprecedented number of neutrino and antineutrino interactions in the 1 GeV $E_{u}$ range. Ongoing analyses in both charged and neutral-current sectors continue to make progress, particularly in understanding (quasi) elastic and single pion production channels. In addition to 6.5E20 protons on target (POT) acquired with a neutrino beam, MiniBooNE has now also collected 3e20 POT in antineutrino mode. An overview of most recent cross-sections results in MiniBooNE will be given.
