In the first part, the Compact Muon Solenoid (CMS) forward calorimeter design studies are presented. The forward calorimeter consists of quartz fibers embedded in a steel absorber. Radiation damage studies of the quartz fiber and the absorber as well as the results of the first pre-production prototype PPP-I are presented. In the second part the Ωc0 search studies at the SELEX (E781) experiment at FermiLab are presented. 107±22Ωc0 events were observed in three decay modes. The relative branching ratio Ωc0 → Ω−π−π+π+)/Β(Ωc0→ Ω−π+)$ is measured as 2.00 ± 0.45 (stat) ± 0.32 (sys).
