Calibration of the momentum scale of a particle physics detector using the Armenteros-Podolanski plot

A method for calibrating the momentum scale in a particle physics detector is described. The method relies on the determination of the masses of the final state particles in two-body decays of neutral particles, which can then be used to obtain corrections in the momentum scale. A modified version of the Armenteros-Podolanski plot and the K-S(0)->pi+pi- decay is used as a proof of principle for this method. A precision at the 10(-6) -10(-8) level is achieved in simplified simulations.
