Abstract
Glueballs are considered to be bound states of constituent gluons. Relativistic wave equation for two massive gluons interacting by the funnel-type potential is analyzed. Using two exact asymptotic solutions of the equation, we derive an interpolating mass formula and calculate glueball masses in agreement with the lattice data. We obtain the complex non-linear Pomeron trajectory, , in the whole region of . The real part of the trajectory corresponds to the soft Pomeron, parameters of which are found from the fit of recent HERA data.
