Abstract 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 → π + π - 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.
