Valence calculation of the electric polarizability on nHYP-Clover ensembles

Abstract

We present preliminary calculations for the electric polarizability of the neutral pion and neutron on three dynamically generated nHYP-Clover ensembles. We use two different pion masses ($m_{\pi }\simeq 300$ and 220 MeV) to gauge the chiral behavior. The effects of partial quenching are analyzed by computing a string of partial quenched valence masses for each ensemble. We also analyzed the volume dependence using elongated lattices, where the elongation is in the direction of the electric field.
