Disagreements for the Omega-sub-b

The two major experimental detectors at Fermilab's tevatron, DZero and CDF, have analyzed recent data and determined that the ?b particle is appearing as predicted by the standard model.

Okay. A particle shows up as predicted. Not so exciting, right? Not quite.

DZero and CDF show that the particle exists by determining a certain mass that the new ?b particle can have. Except DZero and CDF disagree on this mass, and the predicted mass of each experiment is outside the error range for the other experiment. Someone is wrong, and it could be one or both experiments. ]
