Meson-baryon scattering lengths in HB$Ï$PT
arXiv:hep-ph/0607100 · doi:10.1103/PhysRevD.75.034003
Abstract
We calculate the chiral corrections to the s-wave pseudoscalar meson octet-baryon scattering lengths $a_{MB}$ to ${\cal O}(p^3)$ in the SU(3) heavy baryon chiral perturbation theory (HB$Ï$PT). Hopefully the obtained analytical expressions will be helpful in the chiral extrapolation of these scattering lengths in the future lattice simulation.
