Double Scaling of Angular Correlations inside Jets

Abstract

Angular correlations of partons have been derived for high energy jets in QCD. Interesting new scaling properties with two redundant variables (jet energy $P$ and jet opening angle $\Theta$) emerge which can be tested within a parton-hadron duality picture. Recent results from LEP support the scaling in $\Theta$; the scaling in both $P$ and $\Theta$ could be tested with jets from deep inelastic scattering or with high $p_T$ jets.
