The Dark Side of Strongly Coupled Theories

Research output: Contribution to journalJournal articleResearchpeer-review


We investigate the constraints of dark matter search experiments on the different candidates emerging from the minimal quasi-conformal strong coupling theory with fermions in the adjoint representation. For one candidate, the current limits of CDMS exclude a tiny window of masses around 120 GeV. We also investigate under what circumstances the newly proposed candidate composed of a -2 negatively charged particle and a $^4He^{+2}$ can explain the discrepancy between the results of the CDMS and DAMA experiments. We found that this type of dark matter should give negative results in CDMS, while it can trigger the detectors of DAMA, if a condition between the mass and the binding energy of the -2 particle with the nucleus of the detector is satisfied.
