Evidence for an $\eta_c(1S)\pi^-$ exotic resonance at LHCb and development of the Experiment Control System for the RICH upgrade
The first Dalitz plot analysis of $B^0 \to \eta_c(1S)K^+\pi^-$ decays using the data collected by the LHCb detector is presented. A satisfactory description of the data is obtained when including a contribution representing an exotic $\eta_c(1S) \pi^-$ resonant state. The significance of thi...
