Scale relations between mesonic and baryonic trajectories are derived. An analysis of the N-, lambda - and sigma -trajectory data is carried out; contributions of the low-energy thresholds and left-hand cut are extracted and leading contributions are recovered. Estimations for the scale coefficients that relate mesonic trajectories with baryonic ones are obtained. (Atomindex citation 11:530062) 收起
