Abstract
We present a study of the decay . We obtain the -odd fraction in the final state at time zero, , the average lifetime of the (, ) system, , and the relative width difference between the heavy and light mass eigenstates, . With the additional constraint from the world average of the lifetime measurements using semileptonic decays, we find and . For the ratio of the and lifetimes we obtain .
