A singular way to search for heavy resonances in missing energy events

Understand

The phase space of visible particles in missing energy events may have singularity structures.

• The singularity variables are devised to capture the singularities effectively for given event topology.
• They can greatly improve the discovery potential of new physics signals as well as to extract the mass spectrum information at hadron colliders.
• Focusing on the antler decay topology of resonance, we derive a novel singularity variable whose distribution has endpoints directly correlated with the resonance mass.
