The magnetic Sachs form factor is extrapolated at six fixed values of Q2 to the physical pseudoscalar masses and infinite volume using a formulation based on heavy-baryon chiral perturbation theory with finite-range regularization. We properly account for omitted disconnected quark contractions using a partially quenched effective field theory formalism. The results compare well with the experimental form factors of the nucleon and the magnetic moments of the octet baryons.en© 2014 American Physical SocietyJournal article003000917810.1103/PhysRevD.89.0745110003352346000052-s2.0-8489955943984527Thomas, A.
