Bose-Einstein correlation to measure the size of event of different types

Bose-Einstein correlations of identical hadrons produced in high- energy pp collisions at the LHC is a good instrument to probe the size of the domain which emits these hadrons in different classes of events. This provides an additional information on the dynamics of multiparticle production. In particular this way we may measure the radius of the colour tube/string which create the secondary pions.
