<i>CP</i>violation in neutral-<i>B</i>-meson decays in the standard and superweak models

The ambiguities in distinguishing the standard model from superweak models using {ital CP}-violating neutral-{ital B}-meson decay asymmetries are discussed.

Abstract

I discuss the ambiguities in distinguishing the standard model from superweak models using CP-violating neutral-B-meson decay asymmetries. There is a significant region of parameter space where it will be difficult to make the distinction even with 100 ${\mathrm{fb}}^{\mathrm{\ensuremath{-}}1}$ of luminosity at the Y(4S).
