Systematically Searching for New Resonances at the Energy Frontier using Topological Models
We propose a new strategy to systematically search for new physics processes
in particle collisions at the energy frontier. An examination of all possible
topologies which give identifiable resonant features in a specific final state
leads to a tractable number of `topological models' per final state and gives
specific guidance for their discovery. Using one specific final state,
, as an example, we find that the number of possibilities is
reasonable and reveals simple, but as-yet-unexplored, topologies which contain
significant discovery potential. We propose analysis techniques and estimate
the sensitivity for collisions with TeV and

Observing Ultra-High Energy Cosmic Rays with Smartphones
We propose a novel approach for observing cosmic rays at ultra-high energy (> 10 18 eV) by repurposing the existing network of smartphones as a ground detector array. Extensive air showers generated by cosmic rays produce muons and high-energy photons, which can be detected by the CMOS sensors of smartphone cameras. The small size and low efficiency of each sensor is compensated by the large number of active phones. We show that if user adoption targets are met, such a network will have significant observing power at the highest energies
