The signal is observed in the form of an enhancement of pairs of same-sign charged particles with small relative four-momentum. The size of the correlated particle emission region is seen to increase significantly with the particle multiplicity of the event.}, organization = {We wish to congratulate our colleagues in the CERN accelerator departments for the excellent performance of the LHC machine.
