Systematization of tensor mesons and the determination of the 2++ glueball
PACS: 12.38.-t, 12.39.Mk, 14.40.-n
Abstract
It is shown that new data on the (JPC=2++)-resonances in the mass range M\sim1700-2400 MeV support the linearity of the (n,M2)-trajectories, where n is the radial quantum number of quark-antiquark state. In this way all vacancies for the isoscalar tensor q\bar q-mesons in the range up to 2450 MeV are filled in. This allows one to fix the broad f2-state with M=2000\pm30 MeV and \Gamma=530\pm40 MeV as the lowest tensor glueball.
