Search for the $X_b$ and other hidden-beauty states in the $\pi^+ \pi^-ϒ$(1S) channel at ATLAS
This thesis primary concerns a search for a hypothetical state — referred to throughout as the $X_b$ — using the ATLAS detector at the LHC. Specifically, the $\pi^+\pi^-ϒ$(1S) channel was reconstructed in the mass ranges between 10.05-10.31 GeV and 10.40-11.00 GeV using the $ϒ(1S) \to \mu^+ \mu^-$ d...
