Measuring Z' couplings at the LHC

Understand

We study the properties of potential new Z' gauge bosons produced through the Drell-Yan mechanism at the LHC.

• Our analysis is performed using a fully differential next-to-leading order QCD calculation with spin correlations, interference effects, and experimental acceptances included.
• We examine the distinguishability of different models and the feasibility of extracting general coupling information with statistical, residual scale, and current parton distribution function error estimates included.
• We extend a previous parametrization of Z' couplings to include parity-violating coupling combinations, and introduce a convenient technique for simulating new gauge bosons on-peak using the concept of basis models.
