D_ee vs M_ee evaluated at the beam pipe for phi background (top panel) and MC signal (bottom panel). Events in the box M_ee(BP).lt.15 MeV and D_ee(BP).lt.2.5 cm are rejected.		bw eps
Spectrum of the pipiee invariant mass after the cuts on the momenta (top panel) and after the cut to reject events with photon conversions (bottom panel) have been applied. The black histogram is the expected distribution, i.e. signal MC (dark grey), $\phi$ background (light grey) and continuum background (white). The three samples have been normalized according to their luminosity.		bw eps
