Gamma-ray constraints on dark-matter annihilation to electroweak gauge and Higgs bosons
Michael A. Fedderke, Edward W. Kolb, Tongyan Lin +1
Dark-matter annihilation into electroweak gauge and Higgs bosons results in -ray emission. We use observational upper limits on the fluxes of both line and continuum -rays fr…
Dark matter coupling to electroweak gauge and Higgs bosons: an effective field theory approach
Jing-Yuan Chen, Edward W. Kolb, Lian-Tao Wang
If dark matter is a new species of particle produced in the early universe as a cold thermal relic (a weakly-interacting massive particle-WIMP), its present abundance, its scatteri…
Probing dark matter couplings to top and bottom at the LHC
Tongyan Lin, Edward W. Kolb, Lian-Tao Wang
Monojet searches are a powerful way to place model-independent constraints on effective operators coupling dark matter to the standard model. For operators generated by the exchang…
