Description
Jets provide one of the primary tools to study the partons inside
protons. The cross section of inclusive jet production is one of the
main observables to study the hard scattering. It is well described by
pQCD in the collinear factorization framework. For proton-proton
collisions at RHIC at a center-of-mass energy
and in this kinematic region, the direct scattering on gluons inside
the colliding protons contributes about a half of the total cross
section. Thus, measuring the inclusive jet cross section at RHIC,
together with the past Deep Inelastic Scattering measurements, can
provide further constraints on the gluon Parton Distribution Function
at high
cross section at mid-rapidity at STAR using the
previous measurement from 2006, improvements include: employing the
anti-
electromagnetic calorimeter acceptance, unfolding of the detector
response, and correcting jet parameters for Underlying Event
contributions.
