Discovery of the pentaquark

“Data from the Large Hadron Collider (LHC) outside Geneva appears to have proved the existence of particles made of five quarks, solving a 50-year-old puzzle about the building blocks of matter, scientists said on Tuesday.” (Source: CBC News)

“The discovery confirms a long-standing prediction due to the theory of the fundamental strong force of subatomic interactions.   I’m excited by this development because it represents a totally new way in which fundamental constituents of matter (quarks and gluons, in this case) organize themselves.  We need to study this effect and learn more about it.”
