 In September 2008, the DØ collaboration reported detection of the , a "double strange" Omega baryon with the measured mass significantly higher than the quark model prediction.In May 2009 the CDF collaboration made public their results on search for based on analysis of data sample roughly four times larger than the one used by DØ experiment.The mass measurements from the CDF experiment were and in excellent agreement with Standard Model predictions, and no signal has been observed at the previously reported value from the DØ experiment.
