A.K.Ichikawa, Kyoto univ.
We have just started not to be in a time blind with construction works.
Activity members come from KEK, Kyoto univ and Tokyo univ.
Systematic shifts on (sin22q23,Dm232) are evaluated with following systematic errors.
Various systematic shifts are shown as a function of true Dm2.
Dashed lines indicate the size of statistical error.
From K2K systematic errors is very important.Contribution of syst. errors on spectrum
* Super-K intrinsic
Energy dependent non-QE/CCQE ratio, NC/CC ratio
energy scale and normalization (comes from FV, PID etc.)
For ne appearance, statistical and Super-K intrinsic error would be dominant. Still update of p.7 table with T2K off-axis flux is important to confirm this.
From K2K systematic errors is very important.Likelihood
Shape term for FCFV 1Rm
Systematic parameter constraint term
Robustness against the hadron production uncertainty will be checked.
En(Super-K) v.s. En(on-axis) will be made, too.
