摘　　要：In this paper, we study the top content of nucleon by analyzing azimuthal asymmetries in lepton-nucleon deep inelastic scattering(DIS), also we search for the Higgs boson associated production channel, tˉt H, at the large hadron-electron collider(LHe C) caused by boson-gluon fusion(BGF) contribution. We use azimuthal asymmetries inγ*Q cross sections in terms of helicity contributions to semi-inclusive deep inelastic scattering to investigate numerical properties of the cos 2? distribution. We conclude that measuring azimuthal distributions caused by intrinsic heavy quark production can directly probe heavy quarks inside nucleon. Moreover, in order to estimate the probability of producing the Higgs boson, we suggest another approach in the framework of calculating tˉt cross section in boson-gluon fusion mechanism. Finally, we can confirm that this observed massive particle is referred to Higgs boson produced by fermion loop.In this paper, we study the top content of nucleon by analyzing azimuthal asymmetries in lepton-nucleon deep inelastic scattering （DIS）, also we search for the Higgs boson associated production channel, ttH, at the large hadron-electron collider （LHeC） caused by boson-gluon fusion （BGF） contribution.
