A MORE MINIMAL MESSENGER MODEL OF GAUGE-MEDIATED SUPERSYMMETRY BREAKING

This Letter addresses a provocative question: ''Can the standard elect roweak Higgs doublets and their color-triplet partners be the messenge rs of a low energy gauge-mediated SUSY breaking?'' Such a possibility does not seem to be immediately ruled out. If so, it can lead to a ver y economical scheme with clear-cut predictions quite distinct from tho se of the conventional gauge-mediated scenario. Namely, we get (i) a s ingle light Higgs below the original SUSY-breaking scale; (ii) tan bet a = 1; (iii) flavor non-universal, but automatically flavor-conserving soft scalar masses; (iv) a light colored scalar with peculiar phenome nology. The familiar mu, problem looses its meaning in this approach. (C) 1997 Published by Elsevier Science B.V.
