Abstract The M 2 variables are devised to extend M T 2 by promoting transverse masses to Lorentz-invariant ones and making explicit use of on-shell mass relations. Unlike simple kinematic variables such as the invariant mass of visible particles, where the variable definitions directly provide how to calculate them, the calculation of the M 2 variables is undertaken by employing numerical algorithms. Essentially, the calculation of M 2 corresponds to solving a constrained minimization problem… Expand
