Observation of $\Xi (1530{)}^0$ Polarization and Determination of Its Electric and Magnetic Moments in $\psi (3686)\to \Xi (1530{)}^0\bar{\Xi }(1530{)}^0$

BESIII Collaboration, M. Ablikim, M. N. Achasov +703

Using the data sample of $2.7\times 10^9$ $\psi (3686)$ events collected with the BESIII detector at the BEPCII collider, we present an observation of the $\Xi (1530{)}^0$ polarization in th…
