Dilepton signatures for B0-anti B0 mixing and the t-quark at panti p colliders

We quantify dilepton signals expected in panti p collider experiments from the decay of canti c, banti b, tanti t, tanti b, banti t heavy quark pairs produced via parton fusion and radiative processes. The banti b signals dominate and it is feasible to measure B0-anti B0 mixing from the ratio of like-sign to unlike-sign dileptons; 10% mixing doubles the unmixed ratio for back-to-back leptons with psub(T) > 5 GeV. The tanti t, tanti b, banti t signals can be selectively extracted by azimuthal and lepton-isolation cuts. (orig.)
