Abstract

The two-particle correlation function used to study Bose-Einstein interferometry is sensitive to the dynamically correlated same-charge pion pairs from the decay chain η′ → ηπ+π−, η → π0π+π−. This is verified for a sample of Monte Carlo generated events, obtained using the Lund model of fragmentation. A method to reject these pairs based on a kinematical analysis of the MC data is presented, thereby opening the possibility to separate the interferometry signal.
