Understand

We have recently established a new method for measuring the mass of unstable particles produced at hadron colliders based on the analysis of the energy distribution of a massless product from their two-body decays.

The central ingredient of our proposal is the remarkable result that, for an unpolarized decaying particle, the location of the peak in the energy distribution of the observed decay product is identical to the (fixed) value of the energy that this particle would have in the rest-frame of the decaying particle, which, in turn, is a simple function of the involved masses.
In addition, we utilized the property that this energy distribution is symmetric around the location of peak when energy is plotted on a logarithmic scale.
The general strategy was demonstrated in several specific cases, including both beyond the SM particles, as well as for the top quark.
