  The algebraic singularity method is a framework for analyzing  collider events with missing energy. It provides a way to draw out a   set of singularity variables that can catch singular features   originating from the projection of full phase space onto the   observable phase space of measured particle momenta. It is a   promising approach applicable to various physics processes with   missing energy but still  requires more studies for use in practice.   Meanwhile, in the double-sided decay topology with an invisible   particle on each side, the MT2 variable has been known to be a useful   collider observable for measuring particle masses from missing energy   events or setting signal regions of collider searches. We investigate   the relation between the two different types of kinematic variables   in double-sided decay topology.
