Evidence for the Decay B-s(0)-}(DsDs(*))-D-(*) and a Measurement of Delta Gamma(CP)(s)/Gamma(s) (Art. No. 091801)
Original language description
We search for the semi-inclusive process B-s(0)-}(DsDs(*))-D-(*) using 2.8 fb(-1) of pp collisions at s=1.96 TeV recorded by the D0 detector operating at the Fermilab Tevatron Collider. We observe 26.6 /- 8.4 signal events with a significance above background of 3.2 standard deviations yielding a branching ratio of B(B-s(0)-}(DsDs(*))-D-(*))=0.035 /- 0.010(stat.) /- 0.011(syst.). Under certain theoretical assumptions, these double-charm final states saturate CP-even eigenstates in the B-s(0) decays resulting in a width difference of Delta Gamma(CP)(s)/Gamma(s)=0.072 /- 0.021(stat.) /- 0.022(syst.).
