Novel approaches to determine $B^{\pm }$ and $B^0$ meson production fractions

Florian Bernlochner, Martin Jung, Munira Khan +2

We propose novel methods to determine the ${\rm Y}(4S)\to B^{+}{B}^{-}$ and ${\rm Y}(4S)\to B^0{\bar{B}}^0$ decay rates. The precision to which they and their ratio are known yields at present a limiti…
