In some class of supersymmetric (SUSY) models, the neutral Wino becomes the lightest superparticle and the Bino decays into the Wino and standard-model particles. In such models, we show that the measurement of the Bino mass is possible if the short charged tracks (with the length of O(10 cm)) can be identified as a signal of the charged-Wino production. We pay particular attention to the anomaly-mediated SUSY-breaking (AMSB) model with a generic form of Kähler potential, in which only the gauginos are kinematically accessible superparticles to the LHC, and discuss the implication of the Bino mass measurement for the test of the AMSB model.
