SUMMARY:The Partonic Picture at High-Energy Lepton Colliders\, Theory 
 Seminar (High Energy/Cosmology)\, Yang Ma\, University of Pittsburgh
DESCRIPTION:After the triumph of discovering the Higgs boson at the CE
 RN Large Hadron Collider\, people are getting increasingly interested 
 in studying the Higgs properties in detail and searching for the physi
 cs beyond the Standard Model (SM). A multi-TeV lepton collider provide
 s a clean experimental environment for both the Higgs precision measur
 ements and the discovery of new particles. In high-energy leptonic col
 lisions\, the collinear splittings of the leptons and electroweak (EW)
  gauge bosons are the dominant phenomena\, which could be well describ
 ed by the parton picture. In the parton picture\, all the SM particles
  should be treated as partons that radiated off the beam particles\, a
 nd the electroweak parton distribution functions (EW PDFs) should be a
 dopted as a proper description for partonic collisions of the initial 
 states. Along this line\, future ultra-high-energy lepton colliders ca
 n be treated as EW version of LHCs. In our work\, both the EW and the 
 QCD sectors are included in the Dokshitzer-Gribov-Lipatov-Altarelli-Pa
 risi (DGLAP) formalism to perturbatively resum the potential large log
 arithms emerging from the initial-state radiation (ISR). I will show t
 he results of QCD jet production as well as some other typical SM proc
 esses at a possible high-energy electron-positron collider and a possi
 ble high-energy muon collider obtained using the PDFs.
