Full jet reconstruction in d + Au and p + p collisions at RHIC

Abstract

The STAR detector is well suited for investigating jet production at RHIC. It has a large acceptance for both charged particles and electromagnetic radiation, so that reconstructed jets contain a large fraction of the particles descending from an initial hard scattered parton. Inclusive jets can be used to measure jT, which characterizes the transverse jet shape. Di-jet angular distributions in d+Au and p+p collisions at RHIC provide a determination of intrinsic and nuclear kT. The most recent results from this analysis based on year 2003 d+Au and p+p data are presented and compared to results of a di-hadron correlation study.
