Search for the Decay B{sup 0} --> {rho}{sup 0} {rho}{sup 0}
The B{sup 0} --> {rho}{sup 0}{rho}{sup 0} decay mode is searched for in a data sample of about 227 million {Upsilon}(4S) --> B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric B factory at SLAC. No significant signal is observed, and an upper limit of 1.1x10{sup -6} (90% C.L.) on the branching fraction is set. Implications on the penguin contribution and constraints on the CKM angle {alpha} with B --> {rho}{rho} decays are discussed. All results are preliminary.
