Detection of Scalar Singlet Dark Matter
MetadataShow full item record
The purpose of this thesis is to consider the phenomenology of the scalar singlet model of dark matter in light of current experimental and observational results. Signals of the model from direct detection methods, indirect detection methods and from collider searches are all computed. Direct nuclear recoil signals are calculated and compared with current experimental bounds. Indirect cosmic ray annihilation signals in the form of gamma rays, positrons, antiprotons and antideuterons are examined and the possibility of detecting a measurable signal is considered. A neutrino signal from the annihilation of singlet dark matter gravitationally captured in massive bodies is also computed. Finally, the production and detection of scalar singlet dark matter in particle colliders like the LHC is considered. It is found that the scalar singlet model is favored by current nuclear recoil experiments and consistent with current indirect detection bounds.
