  In high-energy collisions, the spatio-temporal size of the particle
production region can be measured using the Bose-Einstein correlations of
identical bosons at low relative momentum. The source radii are typically
extracted using two-pion correlations, and characterize the system at the last
stage of interaction, called kinetic freeze-out. In low-multiplicity
collisions, unlike in high-multiplicity collisions, two-pion correlations are
substantially altered by background correlations, e.g. mini-jets. Such
correlations can be suppressed using three-pion cumulant correlations. We
present the first measurements of the size of the system at freeze-out
extracted from three-pion cumulant correlations in pp, p-Pb and Pb-Pb
collisions at the LHC with ALICE. At similar multiplicity, the invariant radii
extracted in p-Pb collisions are found to be 5-15% larger than those in pp,
while those in Pb-Pb are 35-55% larger than those in p-Pb. Our measurements
disfavor models which incorporate substantially stronger collective expansion
in p-Pb as compared to pp collisions at similar multiplicity.
