Abstract
We consider the production of e +e − pairs occurring in p p collisions from Z production followed by the chain decays: Z → ( se) + ( se ); ( se) → e + γ . (se) denotes the scalar supersymmetric partner of the electron and γ the photino. For a scalar electron mass m = 20 GeV and in correspondence to one hundred e +e − events at the Z peak, we estimate that one should observe about 17 (7) pairs in the invariant mass range 10–70 GeV, with a missing p T larger than 15 GeV (25 GeV) due to the unobserved photinos. For m = 40 GeV, the events reduce to 3 (2) in the same invariant mass and p T intervals. A meaningful search for the scalar electron in the mass range 20–40 GeV seems thus to be feasible, in a high (but realistic) luminosity run at the CERN collider.
