A simple method to determine charge-dependent curvature biases in track reconstruction in hadron collider experiments
Abstract A new data-driven method, using $$Z\rightarrow \mu ^+\mu ^-$$ 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...
