    abstract = "We report the observation of the exclusive decay B-s(0)-> Ds-Ds+ at the
7.5 standard deviation level using 355 pb(-1) of data collected by the
CDF II detector in p (p) over bar collisions at root s =1.96 TeV at the
Fermilab Tevatron. We measure the relative branching ratio B(B-s(0)->
Ds-Ds+)/B(B-0 -> D-Ds+)=1.44(-0.44)(+0.48). Using the world average
value for B(B-0 -> D-Ds+), we find B(B-s(0)->
Ds-Ds+)=(9.4(-4.2)(+4.4))x10(-3). This provides a lower bound Delta
Gamma(CP)(s)/Gamma(s)>= 2B(B-s(0)-> Ds-Ds+)> 1.2x10(-2) at 95% C.L."
