Abstract

We analyze in detail the supersymmetric contributions to the decay of an extra (Formula presented) boson in effective rank 5 models, including the important effect of D terms on sfermion masses. The inclusion of supersymmetric decay channels will reduce the (Formula presented) branching ratio to standard model particles, resulting in lower (Formula presented) mass limits than those often quoted. In particular, the supersymmetric parameter space motivated by the recent Fermilab (Formula presented) event and other suggestive evidence results in a branching fraction (Formula presented)–4 %. The expected cross sections and branching ratios could give a few events in the present data and we speculate on the connection to the three (Formula presented) events observed at Fermilab with large dielectron invariant mass.
