Description
The electric and magnetic polarizability of hadrons encodes information on their internal structure. Traditionally, the background field method has been used to calculate polarizabilities. However, recent work has demonstrated the effectiveness of using four-point functions for computing polarizabilities of charged and neutral hadrons. Our previous work employed a quenched Wilson action on a lattice with pion masses ranging from 1100 MeV to 370 MeV. In this work, we have employed a number of improvements, including a dynamical action (nHYP), smaller pion masses (220 MeV and 315 MeV), and a number of lattice volumes.
