Abstract
From an analysis of the decay , we obtain the width difference between the light and heavy mass eigenstates and the -violating phase . Under the hypothesis of no violation (), we obtain and . The data sample corresponds to an integrated luminosity of about accumulated with the D0 detector at the Fermilab Tevatron collider. This is the first direct measurement of the -violating mixing phase in the system.
