Supersymmetric Decays of the Z' Boson

Understand

The decay of the Z' boson into supersymmetric particles is studied.

• We investigate how these supersymmetric modes affect the current limits from the Tevatron and project the expected sensitivities at the LHC.
• Employing three representative supersymmetric Z' models, namely, E_6, U(1)_{B-L}, and the sequential model, we show that the current limits of the Z' mass from the Tevatron could be reduced substantially due to the weakening of the branching ratio into leptonic pairs.
• The mass reach for the E_6 Z' bosons is about 1.3-1.5 TeV at the LHC-7 (1 fb^{-1}), about 2.5 - 2.6 TeV at the LHC-10 (10 fb^{-1}), and about 4.2 - 4.3 TeV at the LHC-14 (100 fb^{-1}).
