Query: Short distance singularities and automatic O($a$) improvement: the cases
  of the chiral condensate and the topological susceptibility   Short-distance singularities in lattice correlators can modify their Symanzik
expansion by leading to additional O($a$) lattice artifacts. At the example of
the chiral condensate and the topological susceptibility, we show how to
account for these lattice artifacts for Wilson twisted mass fermions and show
that the property of automatic O($a$) improvement is preserved at maximal
twist.
