It is known that the parity-odd (P-odd) observables without spin measurements are naive-T-odd at the same time, and the naive-T-odd distributions arise from the absorptive part of the scattering amplitudes. We study the P-odd and naive-T-odd asymmetries at the one-loop level in W+jet production and top-quark radiative decay processes, and their observabilities at collider experiments such as the LHC and the ILC, by using the loop-level event generator and realistic simulation tools. We find that the expected accuracies in these experiments are enough to observe these asymmetries. By comparing with the theoretical calculation, our understandings of the perturbative calculation on the absorptive part of the scattering amplitude can be studied.
