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…
Using the Energy Spectrum at DAMA/LIBRA to Probe Light Dark Matter
Spencer Chang, Aaron Pierce, Neal Weiner
A weakly interacting massive particle (WIMP) weighing only a few GeV has been invoked as an explanation for the signal from the DAMA/LIBRA experiment. We show that the data from DA…
Inelastic Dark Matter in Light of DAMA/LIBRA
Spencer Chang, Graham D. Kribs, David Tucker-Smith +1
Inelastic dark matter, in which WIMP-nucleus scatterings occur through a transition to an excited WIMP state ~ 100 keV above the ground state, provides a compelling explanation of…
Visible Cascade Higgs Decays to Four Photons at Hadron Colliders
Spencer Chang, Patrick J. Fox, Neal Weiner
The presence of a new singlet scalar particle a can open up new decay channels for the Higgs boson, through cascades of the form h -> 2a -> X, possibly making discovery through sta…
