On-shell constructibility of tree amplitudes in general field theories
Timothy Cohen, Henriette Elvang, Michael Kiermaier
We study "on-shell constructibility" of tree amplitudes from recursion relations in general 4-dimensional local field theories with any type of particles, both massless and massive…

Changes in Dark Matter Properties After Freeze-Out
Timothy Cohen, David E. Morrissey, Aaron Pierce
The properties of the dark matter that determine its thermal relic abundance can be very different from the dark matter properties today. We investigate this possibility by couplin…

Testing a U(1) Solution to the Mu Problem
Timothy Cohen, Aaron Pierce
We discuss the collider phenomenology of TeV Z' gauge bosons related to the absence of a bare mu-term in the superpotential. Decays of the type Z' --> Higgsinos can directly test w…
