Description

The usefulness of the $B_s^0 \to D_s^-a_1^+, D_s^- \to ϕπ^- \to K^+K^-π^-, a_1^+ \to ρ^0 π^+ \to π^+ π^- π^+$ decay chain is investigated for the $B_s$-reconstruction in the future ATLAS $B_s$-mixing experiment. It is shown that this decay channel is almost as suitable for this purpose as previously studied $B_s^0 \to D_s^-π^+$.
