The unexplored landscape of two-body resonances

Understand

We propose a strategy for searching for theoretically-unanticipated new physics which avoids a large trials factor by focusing on experimental strengths.

• Searches for resonances decaying into pairs of visible particles are experimentally very powerful due to the localized mass peaks and have a rich history of discovery.
• Yet, due to a focus on subsets of theoretically-motivated models, the landscape of such resonances is far from thoroughly explored.
• We survey the existing set of searches, identify untapped experimental opportunities and discuss the theoretical constraints on models which would generate such resonances.
