Description
We present an analysis of the pion-nucleon sigma term on the CLS ensembles with $N_f = 2 + 1$ flavors of ${\cal O}(a)$-improved Wilson fermions. We perform a chiral interpolation based on ensembles with pion masses ranging from 130 MeV to roughly 350 MeV. The analysis covers four lattice spacings between $a\approx 0.05\mathrm{fm}\ldots0.09\mathrm{fm}$, allowing for an estimate of systematics associated with lattice artefacts.
