• We study the single longitudinal-spin asymmetries in lepton-pair production with large transverse-momentum at RHIC and J-PARC experiments. Asymmetries in the azimuthal angular distribution of a lepton can arise from an absorptive part of the production amplitudes. We reconsider the one-loop calculation for the absorptive part of the production amplitudes in perturbative QCD and show that the asymmetries can be significantly large in the RHIC and J-PARC experiments.
