Finite Volume Effects of Baryon Properties — •Tim Wollenweber and Thomas R. Hemmert — Technische Universität München

To compare lattice QCD simulations to chiral extrapolations, we utilize Chiral Effective Field Theory with explicit delta degrees of freedom. We calculate the volume dependence of the nucleon mass at O(є³) in the smale scale expansion extending the work of [1]. We also present a calculation for the difference between the finite and infinite volume of the nucleon axial coupling constant g_A in the same formalism extending the work of [2].
