Spin in Strong Interactions

摘要: In this chapter, the basic theoretical relations underlying design and analysis of polarization experiments involving strong interactions are reported on classical examples pion–nucleon nucleon–nucleon scattering. After introduction density matrix reaction matrix, we discuss such notions as complete set equality \(\vec{P}\) in direct asymmetry \(\vec{A}\) inverse example simple system. On system, present method for explicitly constructing formulate unitarity condition, point to possibilities seeking effects parity time reversal violation. The presentation is primarily based technique nonrelativistic quantum mechanics. Relativistic elastic scattering matrices discussed concluding sections. inclusion relativistic insignificantly changes results.
