Gluballs in the String Quark Model
L. D. Soloviev
Abstract
It is shown that the eigenstates of the quantized simplest closed (elliptic) Nambu -- Goto string, called glueballs, have quantum numbers IGjPC=0+j++. Lightest glueballs have spins j=0,1 and 2 and the same mass 1500 +/- 20 MeV. They correspond to f0(1500), f1(1510) and f2(1565)- mesons. Next glueballs have j=0,1,2,3,4 and the same mass 2610 +/- 20 MeV. The slope of the glueball Regge trajectories is twice as small as for q q-mesons. The intersept of the leading glueball trajectory - the pomeron Regge trajectory - is 1.07 +/- 0.03
