Supplemental Figures

Schematic representation of the production of X(5568) with a prompt decay to Bs0 and π± and subsequent decays Bs0 → J/ψ φ, J/ψ → μ+ μ- and φ → K+ K-.
B16AS02

(eps) (jpeg)
Comparison of the m(Bs0π) mass shapes for backgrounds modeled using a simulated sample of events that include the decay Bs0 → J/ψ φ (histogram) and the Bs0 sideband in data (points with error bars) events.

(eps) (jpeg)
The m(Bs0π) distribution together with the background distribution and the fit results after inverting the cone cut.
B16AS04

(eps) (jpeg)
The ratio of the MC background distributions with and without cone cut ΔR < 0.3 vs m(Bs0π).

The data (shown in the red data points) are compared with the background model (shown as the blue histogram) for the mass range M(Bs0π) > 5.6, above the X(5568). The plot on the left shows this comparison for the baseline sample with the ΔR < 0.3 cut; the plot on the right is for the sample with no cone cut.
