Abstract：
Instantons can induce characteristic events in deep-inelastic e⁺p scattering. Such effects are expected to become sizable in QCD. In the present paper QCD-instanton induced events are modelled by the Monte Carlo generator QCDINS. Different methods to reconstruct the instanton part and the current jet are tried in the boson-gluon fusion events of deep-inelastic e⁺p scattering with instantons as background, using QCDINS Monte Carlo event generator. A comparison among these methods are performed and an optimum method is proposed, which can reconstruct well the energies of current jet and instanton as well as the mass of instanton. The proposed method will be useful in the Monte Carlo study of the physical properties of instanton, and can serve as a reference in the experimental identification of instanton.
