Description
The electromagnetic polarizability is an import property of nucleon. It describes the reponse of a nucleon when it is placed in an external eletric or magnetic field. The polarizability can be extracted from the real or virtual Compton scattering process γN → γN. We develop a method to calculate the the Compton scattering matrix elements of nucleon from a 4-point correlation function on the lattice. Then we show that the electromagnetic polarizabilities can be extracted from the lattice data subsequently.
