Spin polarisability of the nucleon at NLO in the chiral expansion
K. B. Vijaya Kumar, Judith A. McGovern, Michael C. Birse
We present a calculation of the fourth-order (NLO) contribution to spin-dependent forward Compton scattering in heavy-baryon chiral perturbation theory. No low-energy constants, ex…

Relativistic Faddeev approach to the NJL model at finite density
M. C. Birse, J. A. McGovern, S. Pepin +1
We study the nucleon solution of the relativistic Faddeev equation as a function of density in the framework of a generalized Nambu-Jona-Lasinio model. We truncate the interacting…
