Observation of High Momentum ${\eta }^{\prime }$ Production in B Decay

T. E. Browder

We report the first observation of $B\to {\eta }^{\prime }X$ transitions with high momentum ${\eta }^{\prime }$ mesons. We observe $39.0\pm 11.6$ B decay events with $2.0<p_{{\eta }^{\prime }}<2.7$ GeV/c, the high momentu…
