Nuclear k_T in d+Au Collisions from Multiparticle Jet Reconstruction at STAR

This paper presents the most recent nuclear k_T measurements from STAR derived from multiparticle jet reconstruction of d+Au and p+p collisions at sqrt(s)=200 GeV. Since jets reconstructed from multiple particles are relatively free of fragmentation biases, nuclear k_T can be measured with greater certainty in this way than with traditional di-hadron correlations. Multi-particle jet reconstruction can also be used for a direct measurement of the fragmentation function.

Full Jet Reconstruction in d+Au and p+p Collisions at RHIC

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 $j_T$, 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 $k_{T}$. 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.
