Description
Multiple fits were done with the run 2 of the LHCb data, to extract signal of
$B_s^0 \rightarrow \phi \phi \phi$ events via charmonia resonances. First, 3D
fits in the bins of the $B_s^0$ invariant mass were computed to get the
estimated number of true $\phi \phi \phi$ events. With a new histogram with the
resulting signal for each bin, a fit was applied, to extract the $B_s^0$
signal. After this fit, from the triggered data of 1972 events, it returned $321.26 \pm 49.3$ events in the signal yields. This procedure also was applied in the bins of the Dalitz plot of the three body decay $B_s^0 \rightarrow \phi \phi \phi$ to then apply a fit of a $\eta_c$ resonance. However due to the low number of events, the yields and uncertainties didn't converged correctly.
