A simple method to determine charge-dependent curvature biases in track reconstruction in hadron collider experiments
Abstract
A new data-driven method, using Z → μ+ μ- 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.
