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