| dc.description | We report a measurement of the rate for $B \to η' X_s$ transitions where the $η'$ meson has center-of-mass momentum in the range 2.0 to 2.7\gevc and $X_s$ represents a system comprising a kaon and up to four pions. Our study is based on 22.2 million $B\bar{B}$ pairs collected at the $Υ(4S)$ with the BABAR detector at the Stanford Linear Accelerator Center. We find $\mathcal{B}(B \to η' X_s)=(6.8^{+0.7}_{-1.7}(stat)\pm1.0(syst)^{+0.0}_{-0.5}(bkg))\times10^{-4}$ assuming that the signal is due to $b \to sg^*$ transitions. | |
