Descripción
Quantum-statistical (Bose-Einstein) two-particle correlations are
measured in p p collisions at √{s }=0.9 , 2.76, and 7 TeV, as well
as in p Pb 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 p Pb interactions and to peripheral PbPb collisions with
multiplicities similar to those seen in p Pb 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.
