Abstract
We have measured the lifetime using the exclusive decay , based on of data collected with the D0 detector during 2002–2006. From 171 reconstructed decays, where the and are identified via the decays and , we measured the lifetime to be . We also measured the lifetime in the decay to be , yielding a lifetime ratio of .
