Angular Distribution of Production Planes in J/ψ→■ Decay
|
摘要
A new observable, the angle between ■ decay planes, is proposed to test the theoretical predictions on the spin correlation. With 10 billion J/ψ events collected with the BES Ⅲ detector at the BEPCⅡ e~+e~- collider, the distribution of the angle could be measured to verify whether or not a correlation exists.
