Abstract
Abstract
A new experimental method to search for T-violating transverse muon polarization (PT
) in the K+
→ π
0
μ
+
ν decay was recently proposed. In this new experiment, the measurements of the μ
+ momentum vector, the π
0 momentum vector, and the μ
+ polarization will be performed by the same segmented calorimeter. One of key issues is the choice of a scintillation material which can maintain the μ
+ spin polarization for several μ
+ lifetimes. A test experiment to measure the μ
+ spin relaxation time in various scintillating materials was carried out at J-PARC Material and Life Science Facility (MLF). It was concluded that the residual μ
+ polarization in CeF3 is high enough to perform the proposed T-violation experiment.
