Measurement of the angular and lifetime parameters of the decays $B_d^0\to J/\psi K^{\ast 0}$ and $B_s^0\to J/\psi \varphi$

D0 Collaboration, V. Abazov

We present measurements of the linear polarization amplitudes and the strong relative phases that describe the flavor-untagged decays $B_d^0\to J/\psi K^{\ast 0}$ and $B_{s}^{0}\to J/ψ…
