CP nonconservation in rare decays of Bs0 mesons
Azimov Ya. I., Ural'tsev N. G., Khoze V. A.
CP-odd effects might be sought in "forbidden" decays of В ° mesons involving a b—>u transition. In the decay of В ° or В ° to the same final state [ p°(0))Ks,K°(y)Ks) etc. ], CP-odd effects should be of order unity in the standard model. The CP nonconservation would be observed most conveniently as a spatial oscillation of the yield in "tracer" beams of В ° mesons. The integrated charge asymmetry of the yield (/ ± + p°Ks) in e+e~ annihilation is expected to be significant with a relatively light Г-quark (xB SI).
