Bose-Einstein correlations and the stochastic scale of light hadrons emitter source
Abstract
Based on quantum field theory at finite temperature we carried out new results for two-particle Bose-Einstein correlation (BEC) function C2(Q) in case of light hadrons. The important parameters of BEC function related to the size of the emitting source, mean multiplicity, stochastic forces range with the particle energy and mass dependence, and the temperature of the source are obtained for the first time. Not only the correlation between identical hadrons are explored but even the off-correlation between non-identical particles are proposed. The correlations of two bosons in 4-momentum space presented in this paper offer useful and instructive complimentary viewpoints to theoretical and experimental works in multiparticle femtoscopy and interferometry measurements at hadron colliders. This paper is the first one to the next opening series of works concerning the searching of BEC with experimental data where the parameters above mentioned will be retrieved.
