Lee-Yang circle analysis for generalized multiplicity distribution

In this work, we study the Lee Yang solutions of multiplicty distribution (MD) generating function for SPS energies range data. In particular, weighted generalized multiplicity distribution (GMD) function is used to describe the existing shoulder structure in the experimental data. Our study suggest that the existence of the shoulder structure in the KNO plot is accompanied by the forming of an ear structure in the Lee-Yang zeros plot. Prediction for the LHC energy range is also made.
