A possible description of the quantum numbers in a hadronic string model

Institute of Theoretical PhysicsUniversity of Stockholm, Box 6730S-113 85 Stockholm, SwedenABSTRACT: We consider a critical composite superconformalstring model to desribe hadronic interactions. We present a newapproach of introducing hadronic quantum numbers in the scat-tering amplitudes. The physical states carry the quantum num-bers and form a common system of eigenfunctions of the opera-tors in this string model. We give explicit constructions of thequantum number operators.
