Bose-einstein correlations in pp, pPb, and PbPb collisions at √sN N = 0.9–7 TeV
Quantum-statistical (Bose-Einstein) two-particle correlations are measured in pp collisions at √s = 0.9, 2.76, and 7 TeV, as well as in pPb and peripheral PbPb collisions at nucleon-nucleon center-of-mass energies of 5.02 and 2.76 TeV, respectively, using the CMS detector at the Large Hadron Colli...

| description | Quantum-statistical (Bose-Einstein) two-particle correlations are measured in pp collisions at √s = 0.9, 2.76,
and 7 TeV, as well as in pPb and peripheral PbPb collisions at nucleon-nucleon center-of-mass energies of 5.02
and 2.76 TeV, respectively, using the CMS detector at the Large Hadron Collider. Separate analyses are performed
for same-sign unidentified charged particles as well as for same-sign pions and kaons identified via their energy
loss in the silicon tracker. The characteristics of the one-, two-, and three-dimensional correlation functions are
studied as functions of the pair average transverse momentum (kT) and the charged-particle multiplicity in the
event. For all systems, the extracted correlation radii steadily increase with the event multiplicity, and decrease
with increasing kT. The radii are in the range 1–5 fm, the largest values corresponding to very high multiplicity
pPb interactions and to peripheral PbPb collisions with multiplicities similar to those seen in pPb data. It is also
observed that the dependencies of the radii on multiplicity and kT largely factorize. At the same multiplicity, the
radii are relatively independent of the colliding system and center-of-mass energy. |
