Jet properties from di-hadron correlations in p+p collisions at s**(1/2) = 200-GeV
Abstract
Description
An analysis of high pT hadron spectra associated with high pT $π^0$ particles in p+p collisions at s**(1/2) = 200-GeV is presented. The shape of the azimuthal angular correlation is used to determine the value of partonic intrinsic momentum $\sqrt{\left<k^2_T\right>} = 2.68 \pm 0.07(\rm stat) \pm 0.34(\rm sys)$ GeV/c. The effect of kT-smearing of inclusive $π^0$ cross section is discussed.
