Momentum Dependent Dark Matter Scattering
Spencer Chang, Aaron Pierce, Neal Weiner
It is usually assumed that WIMPs interact through spin-independent and spin-dependent interactions. Interactions which carry additional powers of the momentum transfer, q^2, are as…
A New Approach to Searching for Dark Matter Signals in Fermi-LAT Gamma Rays
Spencer Chang, Lisa Goodenough
Several cosmic ray experiments have measured excesses in electrons and positrons, relative to standard backgrounds, for energies from ~ 10 GeV - 1 TeV. These excesses could be due…
Displaced Dark Matter at Colliders
Spencer Chang, Markus A. Luty
Models in which the dark matter is very weakly coupled to the observable sector may explain the observed dark matter density, either as a "superWIMP" or as "asymmetric dark matter.…
Discovering a Nonstandard Higgs in a Standard Way
Spencer Chang, Thomas Gregoire
In this note, we explore the Tevatron and LHC detection prospects for a nonstandard Higgs whose decays contain both missing and visible energy. In particular, we consider the decay…
Fake Dark Matter at Colliders
Spencer Chang, Andre de Gouvea
If the dark matter (DM) consists of a weakly interacting massive particle (WIMP), it can be produced and studied at future collider experiments like those at the LHC. The productio…
