Finite-volume and partial quenching effects in the magnetic polarizability of the neutron

Understand

There has been much progress in the experimental measurement of the electric and magnetic polarizabilities of the nucleon.

• Similarly, lattice QCD simulations have recently produced dynamical QCD results for the magnetic polarizability of the neutron approaching the chiral regime.
• In order to compare the lattice simulations with experiment, calculation of partial quenching and finite-volume effects is required prior to an extrapolation in quark mass to the physical point.
• These dependencies are described using chiral effective field theory.
