Searches for final states expected in                                          
models with light gravitinos                                                   
have been performed, including                                                 
experimental topologies                                                        
with multi-leptons                                                             
with missing energy, leptons and photons with missing energy,                  
and jets and photons with missing energy.                                      
Cases with long-lived particles are also considered.                           
No excess over the                                                             
expectations from the Standard Model has been observed.                        
Limits are placed on production cross-sections in the                          
different experimental topologies.
