A simple method to determine charge-dependent curvature biases in track reconstruction in hadron collider experiments

Understand

A new data-driven method, using $Z \rightarrow \mu^+ \mu^-$ decays, is proposed to correct for charge-dependent curvature biases in spectrometer experiments at hadron colliders.

• The method is studied assuming a detector with a "forward-spectrometer" geometry similar to that of the LHCb experiment, and is shown to reliably control several simplified detector mis-alignment configurations.
• The applicability of the method for use in measurements of precision electroweak observables is evaluated.
