title: Hadronic single inclusive k perpendicular distributions inside one jet beyond the modified-leading-log approximation.
abstract: The hadronic k( perpendicular) spectrum inside one jet is determined including corrections of relative magnitude [see formula] with respect to the modified-leading-logarithmic approximation (MLLA), at and beyond the limiting spectrum (assuming an infrared cutoff Q(0)=Lambda(QCD) and Q(0) not equalLambda(QCD)). The agreement between our results and preliminary measurements by the CDF Collaboration is impressive, much better than at MLLA, pointing out very small overall nonperturbative contributions.
