ππ Bose-Einstein Correlation at AGS Energies

  • The study of Bose-Einstein correlations between two identical particles offers a powerful probe to the space-time evolution of ultrarelativistic nucleus collisions.We calculate the correlation function of ππ due to the four space-time and four-momentum distributions of π-at freeze-out in hadronic cascade simulation of 28Si(14.6 A GeV/c)+Au reactions.The correlation function calculated by Fourier transformation method,the correlation function resulted from fullcalculation and the corresponding experimental correlation function agree each other very well.The above freeze-out configuration of π is also used to calculate the root mean square length of π source.These lengths are compared with the conventional fitted radius parameters of source.

Abstract: The study of Bose-Einstein correlations between two identical particles offers a powerful probe to the space-time evolution of ultrarelativistic nucleus collisions.We calculate the correlation function of ππ due to the four space-time and four-momentum distributions of π-at freeze-out in hadronic cascade simulation of 28Si(14.6 A GeV/c)+Au reactions.The correlation function calculated by Fourier transformation method,the correlation function resulted from fullcalculation and the corresponding experimental correlation function agree each other very well.The above freeze-out configuration of π is also used to calculate the root mean square length of π source.These lengths are compared with the conventional fitted radius parameters of source.
