This paper presents a search for anomalous production of
multiple low-energy leptons in association with a W or Z boson using
events collected at the CDF experiment corresponding to 5.1 fb-1
of integrated luminosity. This search is sensitive to a wide range of
topologies with low-momentum leptons, including those with the leptons
near one another. The observed rates of production of additional electrons
and muons are compared with the standard model predictions. No indications
of phenomena beyond the standard model are found. A 95% confidence level
limit is presented on the production cross section for a benchmark model
of supersymmetric hidden-valley Higgs production. Particle identification
efficiencies are also provided to enable the calculation of limits on
additional models.
