Abstract
We report the observation of the in the channel, with decaying to , in collisions at . Using approximately of data collected with the Run II D0 detector, we observe candidates. The mass difference between the state and the is measured to be . We have investigated the production and decay characteristics of the and find them to be similar to those of the state.
