Looking from the east at an elephant trotting west:: direct CP violation in B0 decays

With the time dependent CP asymmetry in B-d(t) --> psi KS well measured, the most powerful method to search for direct CP violation in B-d decays is to analyze whether the CP asymmetry of other transitions like B-d(t) --> pi(+)pi(-), eta'K-S, etc., can be described by a sin term taken from B-d(t) --> psiK(S) and without a cos term. The failure of such a constrained fit would establish direct CP violation (even if no CP asymmetry were observed in these other modes). (C) 2002 Elsevier Science B.V. All rights reserved.
