The {Lambda}{sub b} baryon has been observed recently by UA1 through its decay {Lambda}{sub b} {yields} J/{psi}{Lambda}{degrees}. Although CDF finds twice as many J/{psi} and observes {Lambda}{degrees} decays, no evidence for an {Lambda}{sub b} signal is seen. The UA1 data supports a lower than expected production P{sub T} for the {Lambda}{sub b}, and therefore, a lower pion P{sub T}, below the observation threshold of CDF. This result suggests that UA1 and CDF are probably not inconsistent, but also that the production models are not quite right.
