CP-violating correlations between lepton-charge and jet-charge in Z→bb̄ events

Correlations that signal direct CP violation in the bottom sector are suggested. They need data on Z→bb̄ events which consist of a bottom hadron decay into an exclusive semileptonic channel hℓν (where h is a hadron), and the other bottom hadron decay into a multi-body final state that manifests as a jet in the opposite hemisphere. Replacing “hlν” by inclusive lepton decay of bottom hadrons allows more data. Even then, the signal may be “too small”, as crudely estimated. With better future estimates, the suggested experiments may reveal important new Physics.
