| Abstract: | We present a variational calculation of 0+－ and 0++ glueball masses in 2+1 dimensional U(1) lattice gauge theory by using a Hamiltonian which possesses exact ground state and correct classical continuum limit.In deep weak coupling region,we obtain that am(0+－) decreases with 1/g2 exponentially and am(0++)=2.78g2. |
