Polarization Experiments — A Theoretical Review

  • Francis Halzen
Part of the Studies in the Natural Sciences book series (SNS, volume 12)

Abstract

I would like to attempt to get two important points across in this necessarily superficial and incomplete theoretical review1 of polarization experiments:
  1. a)
    I would like to emphasize their versatility and their relevance to a large variety of aspects of hadron physics. I will discuss polarization measurements as
    • tests of basic symmetries (parity, time reversal ......)

    • a probe of strong interaction dynamics (e.g. in inclusive reactions)

    • a tool for doing hadron spectroscopy (N* spectra, baryonium and di-baryon resonances, multiquark (?) states .....).

     
  2. b)

    I would like to present a qualitative picture of the wealth of experimental data on polarization parameters in pp and np scattering in the Regge language and in the diffraction language, emphasizing the overlap in basic assumption of the two approaches once the veil of their different language has been lifted. More important, both approaches agree that polarization data at medium energy do reveal the structure of the high energy diffractive amplitudes.
