  author={Nikolai I. Kochelev and Albert de Roeck},
A new mechanism for an increased event production in the large Q, x region at HERA is suggested. This mechanism results from a new type of instanton-induced quark-quark interaction, which is related to non-zero quark modes in the instanton field. We estimate the contribution of this interaction to the valence quark structure function F v 2 using the gas… CONTINUE READING
