Varying the Continuum Contribution to the Dielectron Mass Spectrum

Initial Normalization

Estimating Drell-Yan contribution from NLO calculation.

Ramona calculated the cross section for DY at NLO and sent the data points to us.  These were first shown in the RHIC II Science Workshop, April 2005, in her Quarkonium

Using Pythia 8 to get b-bbar -> e+e-

We used Pythia 8 to produce b-bbar events. First we used the default Pythia 8.
