Joint Angular Distribution of B_s -> J/ψϕwith Subsequent ϕ-> ρπand J/ψ-> \ell^+ \ell^- Decays

Abstract

The covariant density matrix formalism is used to obtain the joint angular distribution of the decay B_s -> J/ψϕ(1020) with subsequent ϕ-> ρπand J/ψ-> \ell^+ \ell^- decays. The result is shown algebraically to be a special case of our previous work on the decay distribution of B_d -> J/ψK_1(1270) with K_1 -> K πand J/ψ-> \ell^+ \ell^-.
