Description

Toponium states that are almost degenerate with Z reveal themselves as a dip and not as a bump in the e+e- cross section (properly smeared over the beam energy spread). This is a consequence of destructive interference between the dominant toponium amplitudes and the non-real Z background amplitude. (orig.)
