An alternative form of supersymmetry with modified experimental signatures

This talk will review recent results in our group on an alternative form of supersymmetry that we have proposed [1,2]. There is a convincing case for some form of supersymmetry, but conventional supersymmetry (SUSY) has been plagued by many unsolved theoretical difficulties since its inception half a century ago. Even more importantly, not a single SUSY superpartner has been observed up to surprisingly high experimental limits. These failures  suggest that it is appropriate to rethink the meaning of supersymmetry at the most fundamental level.  Here we consider a radically different form (called susy here to avoid confusion), which initially combines standard Weyl fermion fields and primitive (unphysical) boson fields. A stable vacuum (with Lorentz invariance) then requires that the initial boson fields, with negative-energy excitations, be transformed into three kinds of scalar-boson fields: the usual complex fields, auxiliary fields, and fields of a new kind. The present formulation suggests that there may be superpartners with masses ~ 1 TeV that can potentially be identified via unconventional experimental signatures. Most dramatically, both squarks and gluinos are stable particles, which can hadronize but not decay. They can then be detected as missing energy accompanied by gluon jets, quark jets, or electroweak particles, or alternatively via second-order (electromagnetic, weak, strong, and Higgs-field) interactions with detector components. The experimental predictions of the present theory include (1) the dark matter candidate of our previous papers, (2) many new fermions with masses not far above 1 TeV, and (3) the full range of superpartners with a modified phenomenology.
