• Hadron-nucleus interaction
• Erraticity
• Gap moment method
• Compound hadrons

Erraticity analysis using the gap moment method is performed using the experimental data of pi(-)-AgBr interactions at 200 and 350 GeV both for pions and compound hadrons (pions + protons). The entropy like quantity S (q) has been calculated at two different energies. The variation of S (q) with q and their dependence on multiplicity of charged particles are investigated also. The study reveals the positive indication of the presence of erratic nature of event-by-event fluctuations of gap distributions of produced pions and compound hadrons in emission angle (cos theta) space in relativistic hadron-nucleus interaction.
