Query: O(a) Improvement of 2D N=(2,2) Lattice SYM Theory   We perform a tree-level O(a) improvement of two-dimensional N=(2,2)
supersymmetric Yang-Mills theory on the lattice, motivated by the fast
convergence in numerical simulations. The improvement respects an exact
supersymmetry Q which is needed for obtaining the correct continuum limit
without a parameter fine tuning. The improved lattice action is given within a
milder locality condition in which the interactions are decaying as the
exponential of the distance on the lattice. We also prove that the
path-integral measure is invariant under the improved Q-transformation.
