Years <strong>of</strong> data accumulation<br />

Figure 1-4. Projected time development for the size <strong>of</strong> the effective tagged sample (dashed red line)<br />

and the error on the amplitude for the sine coefficient (solid red line) for a fit to the time-dependent CP<br />

asymmetry in a B 0 → π + π − sample accumulated at a Super B Factory . Tagging efficiencies and per event<br />

errors are based on current BABAR analysis. Also shown are effective tagged samples and the error on the<br />

amplitude for the sine coefficient for LHCb (dashed blue curves) and BTeV (dotted purple curves), based<br />

on their simulations <strong>of</strong> tagging efficiencies and per event sensitivities.<br />

Figure 1-5. Projected time development for the size <strong>of</strong> the effective tagged sample ( --- )andthe<br />

correction to the effective value <strong>of</strong> alpha ( ——)as determined from a full isospin analysis <strong>of</strong> the two-body<br />

B decay modes for a Super B Factory. Tagging efficiencies and per event errors are based on current BABAR<br />

analysis.<br />
