Title: Multiplicity Dependence of Jet Structures in pp Collisions and a
Characteristic Jet Size


Abstract: We study the modification of jet structures in pp collisions
using Monte Carlo event generators. We show evidence for a non-trivial
jet shape dependence on the charged hadron event multiplicity is given
that may be used as a sensitive tool to experimentally differentiate
between equally well-preforming simulation tunes. We show that
multi-parton interactions have a significant effect on the jet shapes.
We propose a characteristic jet size measure which is independent of the
choice of the simulation parameters, parton distribution functions, jet
reconstruction algorithms and even of the presence or absence of
multi-parton interactions. A study of heavy-flavor jets is also
presented where we show the sensitivity of the multiplicity-differential
jet structure to flavor-dependent fragmentation.
