Double-lepton polarization asymmetries in Λb→Λℓ+ℓ- decay are calculated in the universal extra dimension (UED) model. It is found that numerous double-lepton polarization asymmetries are very sensitive to the UED model and therefore can be a very useful tool for establishing new physics predicted by the UED model.
