## Lattice Investigation of the DMO Sum Rule

An evaluation of charged pion polarizability using correlation functions measured on a 16^{3}\times 24 lattice in the context of the Das, Mathur, Okubo (DMO) sum rule is carried out. The calculation is limited to the so-called intrinsic part of the polarizability. This contribution, equivalent to a Euclidean time integral over vector and axial vector momentum-differentiated propagators, is evaluated in both a continuous and discrete sense. In the continuous case, the time behavior of the correlation functions is fit to the continuum quark model; the discrete case is handled by a straightforward application of Simpson's rule for integration after subtracting the pion contributions. A comparison of the implied vector meson and pion decay constants with phenomenological values is carried out. Results for the intrinsic polarizability are...
