Currently 3 Groups are working at CMS

-Lafex/CBPF (Rio) -UERJ (Rio) -IFT/Unesp (São Paulo)

IFT working only on Grid related projects.

CBPF mostly working on software projects• Muon simulation• Castor Database• Offline DQM

UERJ working on software/hardware projects• Castor Software/ Hardware• Muon simulation
