Long Range Electromagnetic Effects Involving Neutral Systems And Effective Field Theory, Br Holstein
Long Range Electromagnetic Effects Involving Neutral Systems And Effective Field Theory, Br Holstein
Barry R Holstein
We analyze the electromagnetic scattering of massive particles with and without spin wherein one particle (or both) is electrically neutral. Using the techniques of effective field theory, we isolate the leading long distance effects, both classical and quantum mechanical. For spinless systems results are identical to those obtained earlier via more elaborate dispersive methods. However, we also find new results if either or both particles carry spin.
