Description

We report a lattice QCD simulation of electric and magnetic polarizabilities of $\pi^0$ using the four-point function method. The connected diagrams are evaluated on the $24^3 \times 48$ lattice using Wilson action with a=0.1 fm and pion mass from 1100 to 370 MeV. Results are compared with existing calculations from the background field method.
