Search for SUSY particles $\text{γ}\text{̃}$, $\text{v}\text{̃}$, $\text{e}\text{̃}$, $\text{W}\text{̃}$ in electron positron annihilation at 44 GeV

Abstract

We study the production of single γ, e and μ at high π_t using the high energy data of the Mark-J detector at PETRA. We find good agreement with QED. We give mass limits of the SUSY particles $\text{γ}\text{̃}$, $\text{v}\text{̃}$, $\text{e}\text{̃}$ and $\text{W}\text{̃}$ studying the associated production of W̃ and ẽ and radiative production of pairs of $\text{γ}\text{̃}$ or $\text{v}\text{̃}$ in three-body reactions.
