Fermilab's CDF team have announced the observation of Ωb , a baryon consisting of two strange quarks and one bottom quark (s-s-b). The existence of this particle was predicted by the Standard Model. However, the mass measurements for this particle are in conflict with results produced by CDF's sister detector, DZero, which had raised the possibility of previously unknown physics possibly in conflict with the Standard Model. Either way, it is exciting. A preprint of the team's Phys. Rev. D. submission is available at arxiv.org.
