Abstract: We calculate the complete T-matrices of pion-nucleon ($\pi N$) scattering to the third order in heavy baryon SU(3)-flavor chiral perturbation theory. The baryon mass in the chiral limit $M_0$ and the low-energy constants (LECs) are… read more here.

Abstract: We discuss the effective field theory description of bound states composed of a heavy baryon and antibaryon. This framework is a variation of the ones already developed for heavy meson-antimeson states to describe the X(3872)… read more here.
