(PhysOrg.com) -- At a recent physics seminar at the Department of Energy`s Fermi National Accelerator Laboratory, Fermilab physicist Pat Lukens of the CDF experiment announced the observation of a new particle, the Omega-sub-b (Ωb). The particle contains three quarks, two strange quarks and a bottom quark (s-s-b). It is an exotic relative of the much more common proton and has about six times the proton`s mass. http://www.physorg.com/news165491925.html Physics Mon, 29 Jun 2009 10:59:17 EST news165491925 (PhysOrg.com) -- Scientists of the CDF experiment at the Department of Energy's Fermi National Accelerator Laboratory announced yesterday that they have found evidence of an unexpected particle whose curious characteristics may reveal new ways that quarks can combine to form matter. The CDF physicists have called the particle Y(4140), reflecting its measured mass of 4140 Mega-electron volts. Physicists did not predict its existence because Y(4140) appears to flout nature's known rules for fitting quarks and antiquarks together. http://www.physorg.com/news156595642.html Physics Wed, 18 Mar 2009 11:48:17 EST news156595642 (PhysOrg.com) -- Thirty years ago, particle physics delighted in discovering the "bottomonium" family -the set of particles that contain both a bottom quark and an anti-bottom quark but are bound together with different energies. Ever since, researchers have sought to ascertain the lowest energy state of these tiny yet important particles. http://www.physorg.com/news134923611.html Physics Thu, 10 Jul 2008 15:46:51 EST news134923611
