Findings

Electroweak decay channels provide clean signals for detection.

Couplings can be probed up to the TeV scale.

Potential for discovery at current collider energies.

Abstract

We explore the phenomenology of an extra U(1) gauge boson which primarily couples to standard model gauge bosons. We classify all possible parity-odd couplings up to dimension 6 operators. We then study the prospects for the detection of such a boson at the LHC and show that the electroweak decay channels lead to very clean signals, allowing us to probe couplings well into the TeV scale.
