In the broken color gauge theory with the lepton-hadron symmetry, the proton structure is analysized in the deep inelastic electron-hadron and muon-proton scatterings. These analysises give correct R behaviour in the electro (muon)-hadron production. The dilepton production in the proton nucleon collision where the parton ideas apply is also studied. The dimuon spectrum and the transverse momentum distribution agree well with the predictions of the broken color gauge theory.
