Systematization of tensor mesons and the determination of the $2^{++}$ glueball | | V. V. Anisovich
; | | Date: |
7 Dec 2004 | | Journal: | JETP Lett. 80 (2004) 715-720; Pisma Zh.Eksp.Teor.Fiz. 80 (2004) 845-849 | | Subject: | hep-ph | | Abstract: | It is shown that new data on the $(J^{PC}=2^{++})$-resonances in the mass range $Msim1700-2400 $MeV support the linearity of the $(n,M^2)$-trajectories, where $n$ is the radial quantum number of quark--antiquark state. In this way all vacancies for the isoscalar tensor $qar q$-mesons in the range up to 2450 MeV are filled in. This allows one to fix the broad $f_2$-state with $M=2000pm30 $MeV and $Gamma=530pm40 $MeV as the lowest tensor glueball.
