Description
We compute the Adler function from vacuum polarization data with
twisted boundary conditions using numerical derivatives. The study is
based on CLS ensembles with two flavours of O(a) improved Wilson
fermions. To describe the momentum dependence and to extrapolate the
lattice data to the continuum limit and to the physical point, we
perform a combined fit and compare our results for the Adler function
to phenomenology. In addition, the Adler function provides an
alternative method to compute the anomalous magnetic moment of the
muon. We compare our results from this approach to a determination
using a more standard method.
