Z' Physics at the LHC
Paul Langacker
The existing limits on Z' gauge bosons and prospects for discovery and diagnostic studies at the LHC are briefly reviewed.
Phenomenological Implications of Supersymmetric Family Non-universal U(1)-prime Models
Lisa L. Everett, Jing Jiang, Paul G. Langacker +1
We construct a class of anomaly-free supersymmetric U(1)' models that are characterized by family non-universal U(1)' charges motivated from E_6 embeddings. The family non-universa…
Electroweak Baryogenesis, CDM and Anomaly-free Supersymmetric U(1)-prime Models
Junhai Kang, Paul Langacker, Tianjun Li +1
We construct two anomaly-free supersymmetric models with a secluded -breaking sector. For the one with embedding we show that there exists a strong enough firs…
Combining Anomaly and Z' Mediation of Supersymmetry Breaking
Jorge de Blas, Paul Langacker, Gil Paz +1
We propose a scenario in which the supersymmetry breaking effect mediated by an additional U(1)' is comparable with that of anomaly mediation. We argue that such a scenario can be…
The Physics of New U(1)' Gauge Bosons
Paul Langacker
Additional Z' gauge bosons are predicted by a wide variety of extensions of the standard model (SM). Possibilities include TeV-scale bosons with electroweak coupling, very light bo…
Six-Lepton Z' Resonance at the Large Hadron Collider
Vernon Barger, Paul Langacker, Hye-Sung Lee
New physics models admit the interesting possibility of a Z' weak boson associated with an extra U(1) gauge symmetry and a Higgs boson that is heavy enough to decay into a pair of…
