Possible signals of wino LSP at the Large Hadron Collider

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 ∼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
