Scientists at TU Wien (Vienna) have calculated that the meson f0(1710) could be a very special particle -- the long-sought-after glueball, a particle composed of pure force. The prediction that glueballs exist is one of the most important of the Standard Model of particle physics that has not yet been confirmed experimentally. For decades, scientists have been looking for so-called "glueballs". Now it seems they have been found at last. A glueball is an exotic particle, made up entirely of gluons -- the "sticky" particles that keep nuclear particles together. Glueballs are unstable and can only be detected indirectly, by...
