The Hyperon Production Mechanism and the Spin Polarization Dynamics

抄録

The spin polarizations of hadrons inclusively produced by pp, γP and νp collisions are studied in the framework of the quark rearrangement model. The present model is a phenomenological one based on the relativistic spin equations of motion and using the quark momentum distribution function in hadrons and photon. A general success of the model is demonstrated. We find usefulness of the present formulation to study the dynamics producing spin asymmetry distributions and the statics determining signs and magnitudes of the spin polarization by reflecting the characteristic quark structure in hadrons.
