Semianalytical Calculation of the O⁺⁺ Glueball Mass in Su(2) Gauge Theory
<p>An attempt is made to derive and to solve the Schrodinger equation in the low energy region (vacuum, first excitation etc.) of the lattice. The complete orthonormal basis in the physical Hilbert space is constructed by classifying independent solutions of the Gauss' law. Loops of elect...
