Momentum Spectrum of ${\eta }^{\prime }$ Meson in the Inclusive Decay $B\to {\eta }^{\prime }{X}_s$

Dong-Sheng Du, Mao-Zhi Yang

The momentum distribution for the ${\eta }^{\prime }$ meson produced through the inclusive decay $B\to {\eta }^{\prime }X$ is investigated under two decay mechanisms, $b\to {\eta }^{\prime }s$ and $b\to {\eta }^{\prime }sg$. Although all t…
