Comment on "Complete One-Loop Analysis of the Nucleon's Spin Polarisabilities"
Michael C. Birse, Xiangdong Ji, Judith A. McGovern
We comment on the paper of Gellas et al, nucl-th/0002027, in which heavy baryon chiral perturbation theory results for the spin polarisabilities of the nucleon are given. That pape…
Spin polarisabilities of the nucleon at NLO in the chiral expansion
Judith A. McGovern, Michael C. Birse, K. B. Vijaya Kumar
We present a calculation of the fourth-order (NLO) contribution to spin-dependent Compton scattering in heavy-baryon chiral perturbation theory, and we give results for the four sp…
