Description
Two-pion Bose-Einstein correlations are often used to extract the radius of the particle emitting source at freeze-out. The extraction of the radii in low multiplicity systems is complicated by the presence of background correlations such as mini-jets. Such backgrounds can be suppressed through the use of three-pion cumulant correlations. We present two- and three-pion Bose-Einstein correlations in pp, p-Pb, and Pb-Pb collisions with ALICE at the LHC. The extracted freeze-out radii are compared in all three systems at similar multiplicity. The results are discussed in view of initial and final state effects.
