Fermilab physicists discover "doubly strange" particle

image
Physicists of the DZero experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory have discovered a new particle made of three quarks, the Omega-sub-b (Ωb). The particle contains two strange quarks and a bottom quark (s-s-b). It is an exotic relative of the much more common proton and weighs about six times the proton mass.

Like children playing a game of tag, some protons and neutrons link up briefly inside the nucleus of the atom and then rapidly split apart. These pairings have now been quantified in the first simultaneous measurement of such pairings and their constituents.

Even though they are among the best-known structures on Earth, the pyramids of Egypt may still hold surprises. This spring, an MIT class is testing a controversial theory that some of the giant blocks that make up the great pyramids of Giza may have been cast in place from concrete, rather than quarried and moved into position.
