Production of Nonlinear SUSY Higgs Bosons at $e^{+}{e}^{-}$ Colliders

Abstract

We investigate the Higgs sector of a nonlinear supersymmetric standard model at LEP 1 and LEP 2, as well as at future linear $e^{+}{e}^{-}$ colliders with $\sqrt{s}=500$, 1000, and 2000 GeV. The LEP 1 data do not put any constraints on the parameters of the model, and allow a massless Higgs boson in particular. For LEP 2, there are remarkable differences between the Higgs productions at $\sqrt{s}=175$ GeV on the one hand and that at $\sqrt{s}=192$ GeV and 205 GeV on the other hand. The case for $\sqrt{s}=175$ GeV is similar to LEP 2, whereas those for $\sqrt{s}=192$ GeV and 205 GeV will be able to give experimental constraints on the parameters. Finally the $e^{+}{e}^{-}$ colliders with $\sqrt{s}=500$, 1000, and 2000 GeV are most probably able to test the model conclusively.
