Measurement of inclusive $D_s$, $D^0$, and $J/\psi$ rates and determination of the $B_s^{(\ast )}{\bar{B}}_s^{(\ast )}$ production fraction in $b\bar{b}$ events at the Y(5S) resonance

A. Drutskoy

The inclusive production of $D_s$, $D^0$, and $J/\psi$ mesons is studied using a 1.86 fb${}^{-1}$ data sample collected on the ${\rm Y}$(5S) resonance by the Belle detector at the KEKB asymme…
