New physics effects through the direct CP violation and the decay rate change are investigated in the semileptonic Dl4 decays, D ± → Kπlν, by including a scalarexchange interaction with a complex coupling. In the decay process, we included various excited states as intermediate states decaying to the final hadrons, K+π, and found that among the intermediate states only the lowest state (K) is dominant and the other higher excited states are negligible, contrary to the Bl4 decays. We also… CONTINUE READING
