Measurement of lifetime and decay-width difference in Bs0→J/ψ decays

We measure the mean lifetime τ=2/(ΓL+ΓH) and the decay-width difference ΔΓ=ΓL-ΓH of the light and heavy mass eigenstates of the Bs0 meson, BsL0 and BsH0, in Bs0→J/ψ decays using 1.7fb-1 of data collected with the CDF II detector at the Fermilab Tevatron pp̄ collider. Assuming CP conservation, a good...
