Abstract: (APS)

Using the expression for the topological charge proposed by Lüscher, we calculate the topological susceptibility in SU(2) lattice gauge theory. This problem has become tractable numerically because we were able to integrate one variable analytically. We verify the validity of this definition at present values of β and compare our results to previous work.
