Glueball masses and Pomeron trajectory in nonperturbative QCD approach

Using a nonperturbative method based on asymptotic behaviour of Wilson loop s we calculate masses of glueballs and corresponding Regge-trajectories. Th e method contains no fitting parameters and the mass scale is fixed by the meson Regge slope. Theoretical predictions for lowest glueball states are i n excellent agreement with lattice results. The leading glueball trajectory and its relation to the Pomeron is discussed in details. important role of mixing between glueball and q (q) over bar trajectories is emphasized.
