Effect of Hadron Contamination on Dielectron Signal Reconstruction in Heavy Flavor Production Measurements

Table 2

Photonic electron yield in the < 0.2 GeV/ mass range for various hadron contamination levels. The statistical uncertainty is 0.05%. The bias is defined as the relative difference between the observed yield and the signal in the pure electron sample.

	Signal	Bias
Electrons only		0
Electrons + 10% hadrons		0.1%
Electrons + 25% hadrons		0.4%
Electrons + 50% hadrons		1.7%
Electrons + 100% hadrons		6.6%
