title = "Quark mass dependence of nucleon observables and lattice QCD",
abstract = "We present an updated analysis of the quark mass dependence of the nucleon mass MN and nucleon axial-vector coupling gA, comparing different formulations of SU(2) Baryon Chiral Effective Field Theory, with and without explicit Δ (1232) degrees of freedom. We discuss the outcome of the corresponding interpolations between lattice QCD data and the physical values for these two nucleon observables. It turns out that in order to obtain successful interpolating functions at one-loop order, the inclusion of explicit Δ (1232) degrees of freedom is not decisive for the nucleon mass but crucial for gA. A chiral extrapolation of recent lattice results by the LHP collaboration is also shown.",
