Description
Multi-parton interactions (MPI) is a key ingredient in the successful
phenomenological description of hadron-hadron collisions. In the
hadronization of MPI, final partons originating from different partonic
sub-collisions can interact with each other through color strings: the
so-called color reconnection (CR) mechanism. In this work we show that
CR produces a radial flow-like effect giving rise to mass ordering. The
study is done within the framework of Pythia 8. We present results for
different observables with identified hadrons in minimum bias pp
collisions at sqrt(s)= 7 TeV. We show that the flow-like effect
increases in events with large MPI activity and therefore with
increasing multiplicity. We discuss how CR generates radial and possibly
elliptic flow and what the role of this mechanism could be in other
systems like p-Pb.
