Query: Long-range two-particle correlations of strange hadrons with charged
  particles in pPb and PbPb collisions at LHC energies   Measurements of two-particle angular correlations between an identified
strange hadron (K0S or Lambda/anti-Lambda) and a charged particle, emitted in
pPb collisions, are presented over a wide range in pseudorapidity and full
azimuth. The data, corresponding to an integrated luminosity of approximately
35 inverse nanobarns, were collected at a nucleon-nucleon center-of-mass energy
(sqrt(s[NN])) of 5.02 TeV with the CMS detector at the LHC. The results are
compared to semi-peripheral PbPb collision data at sqrt(s[NN]) = 2.76 TeV,
covering similar charged-particle multiplicities in the events. The observed
azimuthal correlations at large relative pseudorapidity are used to extract the
second-order (v[2]) and third-order (v[3]) anisotropy harmonics of K0S and
Lambda/anti-Lambda particles. These quantities are studied as a function of the
charged-particle multiplicity in the event and the transverse momentum of the
particles. For high-multiplicity pPb events, a clear particle species
dependence of v[2] and v[3] is observed. For pt < 2 GeV, the v[2] and v[3]
values of K0S particles are larger than those of Lambda/anti-Lambda particles
at the same pt. This splitting effect between two particle species is found to
be stronger in pPb than in PbPb collisions in the same multiplicity range. When
divided by the number of constituent quarks and compared at the same transverse
kinetic energy per quark, both v[2] and v[3] for K0S particles are observed to
be consistent with those for Lambda/anti-Lambda particles at the 10% level in
pPb collisions. This consistency extends over a wide range of particle
transverse kinetic energy and event multiplicities.
