What Is a Glueball?
Chinese Led Team Finds Rare Particle Made Entirely of Force A team of researchers led by China has made a groundbreaking discovery in particle physics: the existence of glueballs, particles composed entirely of force carriers that bind quarks together.
The finding was announced at the International Conference on High Energy Physics in Natal, Brazil. The concept of glueballs has been a cornerstone of theoretical physics for over five decades.
