  "abstract": "Using a dataset corresponding to an integrated luminosity of $9 \\,\\textrm{fb}^{-1}$ collected in proton-proton collisions between 2011 and 2018 by the LHCb experiment, evidence is found for the decay $B^0_s\\toϕη'$ with $3.5 σ$ significance. The branching ratio relative to the $B^0_s\\toϕϕ$ decay is determined to be $R=(3.56 \\pm 0.79\\pm 0.18\\pm 0.06)\\times10^{-2}$. This corresponds to a branching fraction, $B(B^0_s\\toϕη')=(0.66 \\pm 0.15 \\pm 0.03 \\pm 0.02) \\times 10^{-6}$ where, in both cases, the first uncertainty is statistical, the second systematic, and the third due to external branching fractions.",
