The -BS(3) approach
Abstract
We present the results of the -BS(3) approach demonstrating that a combined chiral and 1/Nc expansion of the Bethe-Salpeter interaction kernel leads to a good description of the kaon-nucleon, antikaon-nucleon and pion-nucleon scattering data typically up to laboratory momenta of plab~500 MeV. We solve the covariant on-shell reduced coupled channel Bethe-Salpeter equation with the interaction kernel truncated to chiral order Q3 and to the leading order in the 1/Nc expansion
