Title:     Constraining Neutrino Oscillation Uncertainties: Measuring Charged Current pi+ Production

Abstract: Over the past decade, our understanding of neutrino physics has improved tremendously.  Neutrinos have gone from simply being viewed as the weak interaction partners of charged leptons to massive, oscillating particles that may hold the key to the matter-antimatter asymmetry of the universe.  The next generation of neutrino oscillation experiments will be able to observe neutrino interactions with unprecedented precision.  As such, our understanding of neutrino interaction cross sections must improve accordingly.  Oscillation measurements are performed using the most common neutrino interaction, the charged current quasi-elastic (CCQE) process.  The largest background to this process is charged current pi+ (CCpi+) production, which must be well understood to precisely extract neutrino oscillation parameters from these measurements.  The MiniBooNE experiment at Fermilab has isolated more CCpi+ events than all previous experiments combined, which will allow for a precise determination of the rate and kinematics of this process.

Stimulants available 15 minutes before the talk.
