Physicists confirm existence of new type of meson

Captured From:  Physicists in the College of Arts and Sciences at Syracuse University have made several important discoveries regarding the basic structure of mesons—subatomic particles long thought to be composed of one quark and one antiquark and bound together by a strong interaction. Recently, Professor Tomasz Skwarnicki and a team of researchers proved the existence of a meson named Z(4430), with two quarks and two antiquarks, using data from the Large Hadron Collidor beauty (LHCb) Collaboration at CERN in Geneva, Switzerland. This tetraquark state was first discovered in Japan in 2007 but was later disputed by a team of researchers … More
