The orbital excitations of baryons

In this paper the model of the rotating string for the description of orbital excitations of nonstrange baryons is discussed. The consideration of them as the oblong bags with quarks or diquarks at the ends of the string is carried out. It is emphasize that results do not depend on the quantitative features of the bag-like structure of the string. In the model with ls-coupling the spectrum of orbital baryon excitations is calculated. The model of rotating string with Thomas precession term for ls-coupling allows to identify the main part of baryon excitations
