摘要
We consider a class of anomaly-mediated supersymmetry breaking models where gauginos acquire masses mostly from anomaly mediation while masses of other superparticles, are from Kahler interactions, which are as large as gravitino mass similar to O(10-100) TeV. In this class of models, the neutral wino becomes the lightest superparticle in a wide parameter region. The mass splitting between charged and neutral winos are very small and experimental discovery of such winos is highly non-trivial. We discuss how we should look for wino-induced signals at Large Hadron Collider. (c) 2006 Elsevier B.V. All rights reserved.
