Limiting heavy-quark and gluonphilic real dark matter

We investigate the phenomenological viability of real spin half, zero, and one dark matter candidates, which interact predominantly with third-generation heavy quarks and gluons via the 28 gauge invariant higher-dimensional effective operators. The corresponding Wilson coefficients are constrained one at a time from the relic density omega DMh2 approximate to 0.1198. Their contributions to the thermally-averaged annihilation cross sections are shown to be consistent with the FermiLAT and H.E.S.S. experiments' projected upper bound on the annihilation cross section in the bb over bar mode. The tree-level gluonphilic and one-loop induced heavy-quarkphilic dark matter (DM) nucleon direct detection cross sections are analyzed. The nonobservation of any excess over expected background in the case of recoiled Xe nucleus events for spinindependent DM-nucleus scattering in XENON-1T sets the upper limits on the 18 Wilson coefficients. Our analysis validates the real DM candidates for the large range of accessible mass spectrum below 2 TeV for all but one interaction induced by the said operators.

Automated summary

This study investigates the phenomenological viability of real spin half, zero, and one dark matter candidates that interact with third-generation heavy quarks and gluons. The validity of these candidates is confirmed through constraint analysis of the corresponding Wilson coefficients and examination of the interaction between dark matter and nucleons.
