Abstract：
The discovery of Higgs boson at the CERN Large Hadron Collider (LHC) symbolizes a great triumph of the Standard Model (SM). Studying the Higgs properties and searching for the physics beyond SM are the next targets at the high-energy frontier. A multi-TeV lepton collider provides a clean experimental environment for both the Higgs precision measurements and the discovery of new particles. In high-energy leptonic collisions, the collinear splittings of the fermions and electroweak (EW) gauge bosons are the dominant phenomena, which could be well described by the partonic picture. All the SM particles should be treated as partons that radiated off the beam particles, and the electroweak parton distribution functions (EW PDFs) should be adopted as a proper description for partonic collisions of the initial states. In our work, we complete of the EW PDF evolution, including both EW and QCD sectors, with the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP) formalism to perturbatively resum the potential large logarithms emerging from the initial-state radiation (ISR). We explore the QCD jet production as well as some other typical SM processes at a possible lepton colliders with the EW PDF approach.
