• Relativistic nucleus-nucleus collision
• event-to-event fluctuation of voids
• second order quark-hadron phase transition

This paper reports a study of fluctuations and possible signature of quark-hadron phase transition in high energy collisions. The study is based on the ring-like and jet-like events for pions produced in O-16-AgBr interactions at 60 AGeV. We have performed two-dimensional analysis (eta-phi space) of fluctuation of voids for two types of azimuthal sub-structures of produced pions (ring-like and jet-like) following connecting void approach given by R. C. Hwa and Q. H. Zhang. The values of two parameters %26quot;c%26quot; and %26quot;s%26quot; reveal different void pattern fluctuation in ring-like and jet-like events, which hints toward different mechanism in their production process.
