Resumen:
We combine the D0 measurement of the width difference between the light and heavy B0smasseigenstates and of the CP-violating mixing phase determined from the time-dependent angular distributionsin the B0s! J=  decays along with the charge asymmetry in semileptonic decays also measuredwith the D0 detector. With the additional constraint from the world average of the flavor-specific B0slifetime, we obtain s  L  H  0:13  0:09 ps1 and jsj  0:700:390:47 or s 0:13  0:09 ps1 and jsj  2:440:470:39. The data sample corresponds to an integrated luminosity of 1:1 fb1accumulated with the D0 detector at the Fermilab Tevatron Collider.
