Findings

Gaugino phases can be measured without ad hoc assumptions.

Gluino and LSP masses can be determined at Fermilab.

Methodology applicable to future superpartner discoveries.

Abstract

Once superpartners are discovered at colliders, the next challenge will be to determine the parameters of the supersymmetric Lagrangian. We illustrate how the relative phases of the gluino, SU(2), and U(1) gauginos and the Higgsino mass parameter mu can be measured at a hadron collider without ad hoc assumptions about the underlying physics, focusing on Fermilab. We also discuss how the gluino and LSP masses can be measured.
