      abstract     = {We investigate topology in lattice simulations of QCD with
                      two flavors of dynamical Wilson fermions. At various sea
                      quark masses we find reasonable agreement between results
                      for the topological charge from fermionic and gluonic
                      definitions, the latter with cooling. We study correlations
                      of the topological charge with light hadronic observables
                      and find effects in the flavor singlet pseudoscalar channel.
                      The quark mass dependence of the topological susceptibility
                      χ is consistent with the leading order small mπ
                      expectation, χ=f2πm2π/4.},
