Effect of pion versus kaon interferometry on the chaotic parameter

In this paper, the advantages of pion versus kaon interferometry as a measure to probe the degree of source coherence are studied by a expanding boson gas model with a harmonic oscillator potential. We investigate the conditions about occurrence of Bose–Einstein condensation and analyze its impacts on the chaotic parameter λ. The results indicate that this finite condensation for pion system decreases the value of λ, but influence slightly for kaon system.
