  An enhancement in the number of strange particles produced in relativistic
heavy ion collisions is expected to coincide with the formation of a deconfined
state of partonic matter. Measurements of transverse momentum spectra for
strange particles emerging from p+p collisions are used as a baseline to which
similar measurements from heavy ion collisions are compared. In addition,
several observations from p+p collisions, such as the variation of <pt> with
particle mass and with event multiplicity, are interesting in their own right.
We present measurements of the transverse momentum spectra and <pt> systematics
for strange and non-strange particles from p+p collisions at sqrt{s}=200 GeV.
We show the dependence of the <pt> on measured charged multiplicity and on
particle mass. We will also demonstrate the ability to scale the transverse
mass spectra of various species onto a single universal curve for our p+p data
(an effect known as mt-scaling) and the failure of this scaling when applied to
our Au+Au data. The work presented here was presented as a poster at Quark
Matter 2004.
