High P2 Spin Theories

  • N. E. Tyurin
Conference paper

Abstract

Before discussing the “theories” it is necessary to define the subject more precisely. The best way to do so is to specify those high P 2 spin effects which must be described by the relevant theories. These effects provide “test facility” for “High P 2 Spin Theories”. They are listed below /1/:
  • rapid increase and large value of analyzing power A observed in large angle pp-scattering at p L = 28GeV/c (BNL);

  • rapid increase of spin-spin correlation parameter A nn(up to 60%) when energy grows from 6 to 12 GeV; there is an indication for oscillations with energy (ANL);

  • single spin asymmetry increase with p up to (20–40)% in inclusive π˚ — production processes in the central region (IHEP, CERN, FNAL).
