Abstract:
The newly observed &Bmacr;( 0)-->&Kmacr;( 0)pi(0) mode is quite sizable while pi(-)pi(+) is rather small. Data also hint at pi(-)pi(0) greater, similarpi(-)pi(+). Though consistent with zero, central values of CP violating asymmetries in K-pi(+,0) and &Kmacr;( 0)pi(-) show an interesting pattern. Taking cue from these, we suggest that, besides gamma identical witharg(V(*)(ub)) being large, the rescattering phase delta in Kpi and pipi modes may be greater than 90 degrees. If this is true, not only the above trends can be accounted for, but one would also find pi(0)pi(0) approximately pi(-)pi(+,0), and the CP asymmetry in &Bmacr;( 0) vs B0-->pi(-)pi(+) could be as large as -60%. These results can be tested in a couple of years.
