Precision study of neutrino cross sections for T2K.
Anti-neutrinos
Unexplored physics territory and important for CP study in T2K-II.
MiniBooNE near detector.

2. Started Physics Run from June 2007.
#Protons achieved: 1.71020 POT (goal: 21020 )
0.991020 POT for n and 0.731020 POT for anti-n
Will finish data taking around August 2008.
First anti-n event

3. Status of Analysis (real n data)
Many kinds of analysis
Find a discrepancy on the muon angle distribution.
 Physics origin.
Study the pion production mechanism. qm
