Measurement during AGS Ramp

Asymmetry vs. beam energy
0.009 < -t < 0.022 (GeV/c)2
  • First analysis of April 12-15 data:   (ps)   (pdf)

    • 0.007 < -t < 0.022 (GeV/c)2
  • All data:   plot (ps)   data file (format: scaled GCC, εphys, εacc, εlum, σstat)

  • All data with fit and averaged between spin flips:   plot (ps)   data file (format: Gγ, ave. εphys, σstat)

    • 0.007 < -t < 0.026 (GeV/c)2
  • All data:   plot (ps)   data file (format: scaled GCC, εphys, εacc, εlum, σstat)

  • All data with fit and averaged between spin flips:   plot (ps)   data file (format: Gγ, ave. εphys, σstat)

  • April 12-13 data:   plot (ps)   data file (format: scaled GCC, εphys, εacc, εlum, σstat)

  • April 14-15 data:   plot (ps)   data file (format: scaled GCC, εphys, εacc, εlum, σstat)

  • April 15-16 data:   plot (ps)   data file (format: scaled GCC, εphys, εacc, εlum, σstat)


    • -t dependence
    Asymmetry from all strips
  • ε vs. -t
  • ratio
    •  definition - ratio of ε for Gγ=46.5 to ε for lower Gγ bin
    Asymmetry from central strips
  • ε vs. -t
  • ratio
    •  defined as above
  • ratio ε all strips over ε cental strips
