Submission + - Fermilab Scientists Discover New Particle (conceivablytech.com)
Fermilab today announced that scientists working at the CDF (Collision Detector at Fermilab) experiment confirmed the observation of a new particle, the Xi-sub-b. The Xi-sub-b is categorized as are baryon, which are formed of three quarks. Commonly known baryons include the proton ( two up quarks and one down quark) as well as the neutron (two down quarks and one up quark). The existence of the Xi-sub-b has been predicted for some time, but it has been observed for the very first time just recently. It is described as a heavy relative of the neutron and is six times heavier than the proton or neutron. Conclusively, it is a member of the bottom baryons.
