Content

We present results on the isovector and isoscalar nucleon axial form factors including disconnected contributions. The light disconnected quark loops have been computed using exact deflation, while the strange and the charm quark loops have been evaluated using the truncated solver method. Techniques such as the summation and the two-state fits have been employed to control the excited states contamination.
