Magnetic polarizability of hadrons from lattice QCD
arXiv:hep-lat/0209128 · doi:10.1016/S0920-5632(03)01524-X
Abstract
We extract the magnetic polarizability from the quadratic response of a hadron's mass shift in progressively small static magnetic fields. The calculation is done on a 24x12x12x24 lattice at a = 0.17 fm with an improved gauge action and the clover quark action. The results are compared to those from experiments and models where available.
