摘要：

It is shown that new data on the (J(PC) = 2(++)) resonances in the mass range M similar to 1700-2400 MeV support the linearity of the (n, M-2) trajectories, where n is the radial quantum number of the quark-antiquark state. In this way, all the vacancies for the isoscalar tensor q(q) over bar mesons in the range up to 2450 MeV are filled in. This allows one to fix the broad f(2) state with M = 2000 +/- 30 MeV and Gamma = 530 +/- 40 MeV as the lowest-tensor glueball. (C) 2004 MAIK "Nauka/Interperiodica".
