Findings
Calculated the forward-backward asymmetry for the anomalous U(1) model.
Showed asymmetry can distinguish this model from others.
Demonstrated how asymmetry constrains model parameters.
Abstract
In the past years many possible extensions of the Standard Model (SM) have been investigated. If one of this model is revealed at the LHC, we will need tools to distinguish it among the many others studied. One possibility to achieve this goal is to utilize the forward-backward asymmetry. In this paper we calculate the asymmetry for a model in which there is an extra U(1) anomalous symmetry. Furthermore, we show that the asymmetry can be used to impose constraints on the free parameters of the model.
