| ABSTRACT: |
Supersymmetric extension of standard model of particle physics is an attractive candidate of TeV energy scale new physics, and an important target of the Large Hadron Collider.
So far, several techniques have been proposed to discover the new physics, and to measure properties of new particles.
Importantly, however, the strategy that we should take depends on the event topology, namely, details of the new physics; particle contents, mass spectrum, and so on.
In this talk, we study the case that the lightest superparticle (LSP) is the gravitino, and in this case, the next-to-lightest superparticle (NLSP) may have very long lifetime.
In addition, if the NLSP is charged particle, it may be possible to directly observe a track of the NLSP in the detectors; this is an characteristic event signal of such a model.
We discuss how we can probe the model by utilizing the charged track of NLSP, paying particular attention to the case that NLSP is the stau. |
