A third virtue of theGSO projection:it leads to space-time supersymmetry. Besides the formal interest, the massless spin 3/2 particle should couple to a current whose conserved charge is spin 1/2, i.e., asupersymmetric charge. Author's Note: What is supersymmetry? These MIA superpartners are really starting to freak out some physicists. It would be a really big deal if we never saw them, because particle physics desperately needs testable theories.

known that moduli fields appearing in the leading order equations will remain massless even if higher order corrections are taken into account [22,23]. In our case, such an analysis has not been performed yet from the spacetime point of view, though the question can be answered from the world-sheet approach recently developed in [18].

We investigate space-time supersymmetry in the WZW-like open superstring field theory, whose complete action was recently constructed. Starting from a natural space-time supersymmetry transformation at the linearized level, we construct a nonlinear transformation so as to keep the complete action invariant. bosons built with an odd number of anticommuting world-sheet fieldsacting, for instance, on a massless vector meson.

The extended supersymmetry can only occur on-shell or if the target space is 4d-dimensional with d>1 [9]. The explicit structure of on-shell N=(4,4) supersymmetry in four dimensions was investigated in a recent paper [10].

ble with space-time supersymmetry, and non-local world-sheet e ects have to be taken into account for resolving this issue consistently. Afterall, it is a well-known fact that symmetries not commuting with a given Killing vector eld are not manifest in the dual background of the e ective eld theory description.

Apr 20, 2014 · String theory strictly speaking requires world sheet supersymmetry, the map to space time Susy requires a few more axioms to also be true, but it's definetely true that it makes things much simpler and most textbook models assume it. May 21, 2013 · In this video, Fermilab's Dr. Don Lincoln describes the principle of supersymmetry in an easy-to-understand way. A theory is supersymmetric if it treats forces and matter on an equal footing.
