Latest Xi baryon Stories

Physicists at the U.S.-based Fermilab have produced a new particle that is a heavier relative of the neutron. The Batavia, Illinois atom smasher found the neutral Xi-sub-b by smashing particles together around a 4-mile ring at near light speed.  Physicists knew the particle existed, but it is the first time researchers have observed it firsthand.  Measuring the properties of particles like the neutral Xi-sub-b allows physicists to understand how quarks interact to form matter. The...

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.The observation of this "doubly strange" particle, predicted by the Standard Model, is...

University of Michigan physicists played a leading role in the discovery of a new particle, the Omega b baryon, which is an exotic relative of the proton. It was detected for the first time in a particle accelerator at Fermi National Accelerator Laboratory (Fermilab) in Illinois, Fermilab has announced.The heavy particle is scarce today, but scientists believe it was abundant soon after the Big Bang."This discovery helps us understand how matter was formed in the universe. It shows the...
