title: Generalized spin polarizabilities of the nucleon in heavy-baryon chiral perturbation theory at order Omicron(p(4)).
abstract: We present the first heavy-baryon chiral perturbation theory calculation at order Omicron(p(4)) for the spin-dependent amplitudes for virtual Compton scattering off the nucleon and extract the Omicron(p(4)) results for the generalized spin polarizabilities of the nucleon.
