New Particle Found, the Bottom-Most Bottomonium

Posted by kdawson on from the how-low-can-you-go dept.

PhysicsDavid writes "Collaborators on the BaBar experiment at the Stanford Linear Accelerator Center have detected and measured, for the first time after a 30-year search, the lowest energy particle of the 'bottomonium' family, called the eta-sub-b. Bottomonium consists of a bottom quark and an anti-bottom quark bound together by the strong force. The discovery fills in a missing piece of quark physics that will help reveal the nature and behavior of the quarks and the strong force."

    Is it any surprise that the most laid back particle evar was discovered in California?

  2. bottom and anti-bottom? by spooje · · Score: 5, Funny

    The bottom and anti-bottom held together by the strong force?

    Sounds cheeky to me
