摘要：

We present theoretical results for the interference effects between solitons and two-magnon processes in the classical sine-Gordon model. We calculate the dynamical longitudinal structure factor where the two-magnon processes give an important contribution to the central peak. We compare our results with existing numerical simulation data.
