Abstract

We estimate the

-B

¯_{d}

and

B_{s}

-B

¯_{s}

mixing effects using computed production cross sections for

B_{q}

¯_{q}

B_{q}

¯_{q}^{*}

+c.c.,

B_{q}^{*}

¯_{q}^{*}

(q=d,s) in the region from Υ(4S) to Υ(7S). It is shown that the mixing signal of same-sign leptons will peak at Υ(5S) under the assumption of standard model estimates, and if the total integrated luminosity of 1000

{pb}^{- 1}

is achieved, it will be observable.
