Abstract
We report on the measurement of two-pion correlation functions from collisions at performed by the ALICE experiment at the Large Hadron Collider. Our analysis shows an increase of the Hanbury Brown–Twiss radius with increasing event multiplicity, in line with other measurements done in particle- and nuclear collisions. Conversely, the strong decrease of the radius with increasing transverse momentum, as observed at the Relativistic Heavy Ion Collider and at Tevatron, is not manifest in our data.
