Abstract

Spin- 1 2 baryons built from massless quarks are considered in the limit of a large number of colors, N → ∞. We obtain a formula expressing the baryon mass m_B in terms of the quark condensate 〈0{divides}qq{divides}0〉. As was anticipated, m_B ∼ N. We discuss also the behavior of the coupling constants g_πNN and g_A and some properties of baryonic and mesonic spectra.
