Electric Polarizabilities from Lattice QCD

Understand

The response of hadrons to electromagnetic probes is highly constrained by chiral dynamics; but, in some cases, predictions have not compared well with experimental data.

• The lattice can be used to test the chiral electromagnetism of hadrons and ultimately confront experiment.
• We use background field techniques to study the electromagnetic polarizabilities of hadrons.
• Focusing on simulations in background electric fields, we present preliminary results for both charged and neutral particle polarizabilities.
