Bose-Einstein correlation and Q-υKυ(Q) distribution

Bose-Einstein correlation is one of the most useful means to study the source emitting hadrons. Based on the non-perturbative theory of quantum fields, we have proposed a kind of source distribution, i.e., the Q-υKυ(Q) distribution, which is applied to calculate single inclusion distribution of P//, Pperpecular, N, Y and the correlation with each other, i.e., Seagull effect. The results have a better approximation to the corresponding experimental data. The paper emphasizes the calculation of Bose-Einstein correlation for inclusive two particle based on the Q-υKυ(Q) distribution. The fitted curves agree with experimental data, especially, in the small Q range. The Q-υKυ(Q) distribution is a more advanced theory as compared with Gauss source and K-P source distribution
