Multipion Bose-Einstein correlations in pp, p-Pb, and Pb-Pb collisions at the LHC

Understand

Three- and four-pion Bose-Einstein correlations are presented in pp, p-Pb, and Pb-Pb collisions at the LHC.

• We compare our measured four-pion correlations to the expectation derived from two- and three-pion measurements.
• Such a comparison provides a method to search for coherent pion emission.
• We also present mixed-charge correlations in order to demonstrate the effectiveness of several analysis procedures such as Coulomb corrections.
