Abstract

The effect of detector-related uncertainties on the determination of the parent particle mass in two-body decays is described. Studies of the biases versus the sum and difference of the daughter particle momenta can be used to determine biases on the mass. The approach is illustrated for the case of measuring the $\Lambda$ hyperon mass.
