Description
I will discuss progress on computing nucleon elastic form factors with the stochastic LapH method.
OR, if results these results are not yet ready,
I will discuss preliminary results on the nucleon-pion sigma term determined with O(30) HISQ ensembles with MDWF valence fermions. The nucleon spectrum results are determined at 7 pion masses in the range 130 < Mpi < 400 MeV, four lattice spacings in the range 0.06 < a < 0.15 fm, and several volumes. The nucleon-pion sigma term is determined through a derivative of the extrapolation of the nucleon mass to the physical point.
