Probing gaugino coannihilation with displaced vertex searches | | Natsumi Nagata
; | | Date: |
2 May 2016 | | Abstract: | Bino-like dark matter in supersymmetric theories tends to suffer from
over-production. This problem can be evaded if there is another gaugino which
has a mass close to the bino mass so that it enhances the annihilation rate of
bino dark matter through coannihilation. We study such possibilities in
high-scale supersymmetric models, and show that searches for long-lived
particles with displaced vertices can test the bino-gaugino coannihilation
scenario in the forthcoming LHC experiments. | | Source: | arXiv, 1605.0585 | | Services: | Forum | Review | PDF | Favorites | |
