Abstract
We present a study of the inclusive production of the state with the decay to the final state in hadronic collisions. Based on of collision data collected by the D0 experiment at the Fermilab Tevatron collider, we report the first evidence for the prompt production of an state and find the fraction of events originating from hadrons to be . The ratio of the nonprompt production rate to the yield in the same channel is . The values of the mass and width are consistent with previous measurements.
