Аннотация:The present-day B-anomalies involving b → sμ+μ− or b → cτ − ̄ν transitions can all be explained with the addition of a vector U1 leptoquark with a mass of MU1 > 1.8 TeV. In the scalar singlet dark matter model (SSDMM), the DM is a scalar S that couples to the Higgs via λhS S**2|H|**2. We update the fit to the data and find that the SSDMM is now viable only for MS > 1.6 TeV. In this paper, we assume that the DMalso couples to the U1 via λ{U_1S} S^2 U†_{1μ}U^μ_1 . In addition to leading to DM annihilation viaSS → U1 ̄U1, this coupling generates SSgg and SSγγ couplings at one loop. Althoughnaively divergent, these loop diagrams can be calculated under the assumption that theU1 is a gauge boson of a group broken at the TeV scale. With this DM-U1 coupling term,there are additional contributions to the various DM observables (relic density, direct andindirect detection). We find that the constraints on the SSDMM are relaxed for both heavyDM (MS & MU1 ) and light DM (MS < MU1 ).
