At small lattice spacing, or when using overlap fermions, lattice QCD simulations tend to become stuck in a single topological sector. Physical observables, e.g. hadron masses, then differ from their full QCD counterparts by 1/V corrections, where V is the spacetime volume. These corrections can be calculated order by order using the saddle point method. We calculate all corrections proportional to 1/V 2 and 1/V 3 and test the resulting equations for several models: a quantum mechanical particle on a circle, the Schwinger model and SU(2) Yang-Mills theory.
