We discuss the possible production and discovery channels in $e^+e^-$ and $pp$ machines of the $X_b$, the bottomonium counterpart of $X(3872)$ and the putative isoscalar analogue of the charged bottomonium-like states $Z_b$ discovered by Belle. We suggest that the $X_b$ may be close in mass to the bottomonium state $\chi_{b1}(3P)$, mixing with it and sharing its decay channels, just as $X(3872)$ is likely a mixture of a $\bar D D^*$ molecule and $\chi_{c1}(2P)$. Consequently, the experiments… Expand

Analysis of X(3872) production via heavy meson effective theory
We analyze the $X(3872)$ production in the processes $ \bar{D} D \rightarrow \pi X $, $\bar{D}^* D \rightarrow \pi X $ and $\bar{D}^* D^* \rightarrow \pi X $, making use of the Heavy-Meson EffectiveExpand
Observation of the χ_{b1}(3P) and χ_{b2}(3P) and Measurement of their Masses.
TLDR
This is the first time that the J=1 and 2 states are well resolved and their masses individually measured, and they are determined with respect to the world-average value of the ϒ(3S) mass, which has an uncertainty of 0.5 MeV. Expand
