Studying baryon production using two-particle angular correlations

Studying baryon production using two-particle angular correlations

Latest measurements of ΔηΔφ correlations of identified particles show differences in particle production between baryons and mesons. The correlation functions for mesons exhibit the expected peak dominated by effects of mini-jet fragmentation and are reproduced well by general purpose Monte Carlo ge...
