Linear Collider Signal of a Wino LSP in Anomaly Mediated Scenarios

Abstract

Selectron (smuon) pair-production in a next generation Linear Collider, yielding a fast electron (muon) trigger, a visible heavily ionizing track and/or a resolved soft pion impact parameter and overall $\mET$, is shown to provide a smoking gun signature for Anomaly Mediated Supersymmetry Breaking models with a neutral Wino as the Lightest Supersymmetric Particle, nearly mass-degenerate with the lighter chargino.

13 pages, LaTeX, 3 postscript figures. Though the results and conclusions remain unchanged, the text and the figures have been substantially modified. Some typos have been corrected and new references added. Discussion added of Standard Model backgrounds which turn out to be very small. The paper will be published shortly in JHEP
