✦ Synopsis

The hadronic k ⊥ -spectrum and the gluon to quark average multiplicity ratio r = Ng/Nq inside a high energy sub-jet are determined from a precise definition of the jet axis, including corrections of relative magnitude O( √ αs) with respect to the Modified Leading Logarithmic Approximation (MLLA), in the limiting spectrum approximation (assuming an infrared cut-off Q0 = Λ QCD ). The results for the k ⊥ -spectrum in the limiting spectrum approximation are found to be, after normalization, in impressive agreement with measurements by the CDF collaboration, and the ratio has not been measured yet.
