A search for supersymmetric electrons with the Mark II detector at PEP
An experimental search for selections, the supersymmetric partner of the electron, has been performed at the PEP storage ring at SLAC using the Mark II detector. Supersymmetry is a theory based upon a symmetry between fermions and bosons, such that all ordinary fermions (bosons) have supersymmetric bosonic (fermionic) partners. This theory is very important in current theoretical attempts to construct a complete unified quantum field theory which incorporates all four forces: strong, electromagnetic, weak, and gravitational. However, all experimental searches for supersymmetric signals, including this one, have so far yielded negative results. The experimental search done was based upon the followed hypothetical reaction in e{sup +}e{sup {minus}} interactions at PEP center of mass energies of 29 GeV. In this reaction the sections, e, are assumed produced by the interaction of one of initial state electrons with a photon radiated from the other initial state electron. This latter electron is assumed to continue down the beam pipe undetected. The photon and electron then produced a selectron and a photino, {gamma}, in the supersymmetric analog of Compton scattering. The photino is assumed to be lightest supersymmetric particle, and as such, does not interact in the detector, thereby escaping detection very much like a neutrino. The selectron is assumed to immediately decay into an electron and a photino.
