Description
"Coherence of pions in the final state is known to suppress Bose-Einstein correlations. The amount of suppression increases for higher order
correlations. We present a new method to measure the coherent fraction of pions using multi-pion Bose-Einstein correlations. The comparison of
two-, three-, and four-pion correlations allows for a more unambiguous measure of the coherent fraction.
We present the measurements in Pb-Pb collisions at sqrt(sNN) = 2.76 TeV with ALICE at the LHC.
We also show how the methodology can be extended for future measurements in smaller systems such as pp and p-Pb."
