List of contributing systematics
Detector Contributions:
Acceptance: Look at previous data using SeaQuest and check for false asymmetries also use Monte Carlo to study phi-modulation
Fiducial Limits: Study detector limitations and necessary cuts
Time Variations: Look at time dependence from gas or field drifts
Accidentals: Study contribution of pion-decay accidental background to the left-right asymmetry
Tracking and Reconstruction Error: Compare background seen in MC and real data
Trigger Inefficiency: Understand efficiency in trigger and expected limitations and asymmetries associated
Change in instrumental noise: Prop tube, chambers, etc...
Beamline Uncertainty:
Luminosity: Variation in luminosity not accounted for
Beam Drifts: Drifts over beam spill or over several hours leading to false left-right asymmetry
Scrapping: Left-right asymmetries induced by beam scrapping
Deadtime: Need accurate accounting for deadtime and efficient monitoring of detectors in this accounting
Target Systematics: (Can be different for proton and deuteron)
Know Uncertainty in polarized target: TE, Temp/pressure measurements, baseline, mag field drifts, charge averaging, NMR tune drifts, area measurements
Dilution Factor: Must be measured and calculated
Packing Fraction: Must be measured and calculated
Initial Polarization Homogeneity: Microwave induced differences
Beam Heating Polarization Effects: Secondaries scatterng off the down stream end might heat things up to lower the polarizaton
Uneven decays in Polarization: The target receives a different dose over its length
