Right. The RegisterPhysics() function takes a G4VPhysicsConstructor* argument, which is one of the components of building a physics list. You've passed it (above) a pointer to a single process. For Cerenkov production, you would need to register G4OpticalPhysics. If you don't need the other optical physics processes, you can disable them via macro commands.
