Query: Single Spin Asymmetry in Heavy Quark Photoproduction (and Decay) as a
  Test of pQCD   We review the properties of the single spin asymmetry (SSA) in heavy quark
production by linearly polarized photons and analyze the possibility to measure
this SSA in the planned E160/E161 experiments at SLAC.
