Testing models of hadron production with strange hadrons in the
intermediate pT region using the STAR detector.

Hadrons observed in the intermediate pT region (2-5 GeV/c) at
RHIC stem from both non-perturbative and perturbative processes.
In this region the hadron spectrum is influenced by the behaviour
of the bulk system at lower pT and from the fragmentation of hard
scattered partons at higher pT. Studying the interplay between 
these two regimes as a function of system size may help to clarify
the effects of the medium on hadron production in Au+Au collisions.

This talk will focus on neutral strange particle production 
(Lambda, AntiLambda and KZero) in p+p, d+Au and Au+Au collisions
at 200 GeV/c per nucleon. The baryon to meson ratio and nuclear
modification factor will be used to explore the relative contributions
of hard and soft processes to the transverse momentum spectrum.
These measurements will be used to test various models of hadron
production in this intermediate pT region.
