CP asymmetries at D0
Description
Using two independent measurements of the semileptonic CP asymmetry in the Bs system, we constrain the CP-violating phase of the Bs system to be φs = -0.70-0.39+0.47. The data sample corresponds to an integrated luminosity of 1.1 fb- accumulated with D0 detector at the Fermilab Tevatron Collider. We also measure the direct CP violating asymmetry in the decay B+ → J/ψK+ to be ACP(B+ → J/ψK+) = +0.0067 ± 0.0074(stat)±0.0026(syst). The data corresponds to an integrated luminosity of 1.6 fb-
