In this article, we calculate QED corrections due to the initial-state photon radiation (ISR) to process e- e+ -> W- W+ -> 4 jets at lepton colliders. The computations are performed up to the correction with order. For physically interpretation, the impact of ISR corrections on total cross sections and its relevant distributions are studied. We find that the corrections are almost 10% of the total cross-section. Thus, these corrections are significant, and they must be taken into account at lepton colliders in the future. | Initial-state photon radiation to e- e+ -> W- W+ -> 4 jets at lepton colliders
