Query: Meson-baryon Scattering in Extend-on-mass-shell scheme at
  $\mathcal{O}(p^3)$   In this present work, we study the scattering of a pseudoscalar meson off one
ground state octet baryon in covariant baryon chiral perturbation theory up to
the next-to-next-to-leading order. We remove the power counting breaking terms
with the extended-on-mass-shell scheme. We perform the first combined study of
the pion-nucleon and kaon-nucleon scattering data and show that the covariant
baryon Chiral perturbation theory can provide a reasonable description of the
experimental data for both channels.
