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

<div>Invariant mass spectrum for foreground (all opposite-sign pairs) and combinatorial background for selected levels of hadron misidentification: (a) “Electrons only,” (b) “Electrons + 25% hadrons,” (c) “Electrons + 50% hadrons,” and (d) “Electrons + 100% hadrons.”</div>
