Decoherence in Excited Atoms by Low-Energy Scattering

Atoms, 2016
We describe a new mechanism of decoherence in excited atoms as a result of thermal particles scattering by the atomic nucleus. It is based on the idea that a single scattering will produce a sudden displacement of the nucleus, which will be perceived by ...

Reconstructing the velocity distribution of weakly interacting massive particles from direct dark matter detection data [PDF]

, 2007
Weakly interacting massive particles (WIMPs) are among the leading dark matter candidates. Currently, the most promising method for detecting many different WIMP candidates is the direct detection of the recoil energy deposited in a low background ...

Material radioassay and selection for the XENON1T dark matter experiment

European Physical Journal C: Particles and Fields, 2017
The XENON1T dark matter experiment aims to detect weakly interacting massive particles (WIMPs) through low-energy interactions with xenon atoms. To detect such a rare event necessitates the use of radiopure materials to minimize the number of background ...

Collider Signatures of SuperWIMP Warm Dark Matter

, 2006
SuperWeakly-Interacting Massive Particles (superWIMPs) produced in the late decays of other particles are well-motivated dark matter candidates and may be favored over standard Weakly-Interacting Massive Particles (WIMPs) by small scale structure ...

(Super) gravity from positivity

Journal of High Energy Physics
We investigate whether the effective theory for isolated, massive, and weakly interacting spin-3/2 particles is compatible with causality and unitarity — i.e., the positivity of scattering amplitudes. We find no solution to positivity constraints, except
