The Mass Gap in 2 + 1 Dimensional SU(2) Lattice Gauge Theory

  • A glueball mass in 2 + 1 dimensional SU(2) lattice gauge theory is calculated by applying variation in the Hamiltonian with exact ground state. In the range 0 ≤ 1/g2 ≤ 7, a good scaling behaviour am = 2.28g2 is obtained, which is in agreement with weak-coupling expansion result.

Abstract: A glueball mass in 2 + 1 dimensional SU(2) lattice gauge theory is calculated by applying variation in the Hamiltonian with exact ground state. In the range 0 ≤ 1/g2 ≤ 7, a good scaling behaviour am = 2.28g2 is obtained, which is in agreement with weak-coupling expansion result.
