Determining wino lifetime in supersymmetric model at future 100 TeV pp colliders
We discuss a possibility to measure the lifetime of charged Wino in supersymmetric model at future 100TeV pp colliders, assuming that (neutral) Wino is the lightest superparticle (LSP). In the Wino LSP scenario, the charged Wino has a lifetime of about 0.2ns, and its track may be reconstructed in pa...

description | We discuss a possibility to measure the lifetime of charged Wino in supersymmetric model at future 100TeV pp colliders, assuming that (neutral) Wino is the lightest superparticle (LSP). In the Wino LSP scenario, the charged Wino has a lifetime of about 0.2ns, and its track may be reconstructed in particular by the inner pixel detectors. We show that the lifetime of charged Wino may be measured by using the information about the distribution of the flight lengths of charged Winos. We propose a procedure for the lifetime determination and show how the accuracy changes as we vary the mass spectrum of superparticle. We also discuss the effects of the detector layouts on the lifetime determination. |
