Resumen | From an analysis of the flavor-tagged decay Bs0→J/ψϕ we obtain the width difference between the Bs0 light and heavy mass eigenstates, ΔΓs=0.19±0.07(stat) +0.02-0.01(syst)ps-1, and the CP-violating phase, ϕs=-0.57 +0.24 -0.30(stat) +0.08 -0.02(syst). The allowed 90% CL intervals of ΔΓs and s are 0.06<ΔΓs<0.30ps-1 and -1.20 <ϕs <0.06, respectively. The data sample corresponds to an integrated luminosity of 2.8fb-1 accumulated with the D0 detector at the Fermilab Tevatron collider. |
