Transverse momentum spectra of charged hadrons in jets at the Tevatron
Abstract
Description
The hadronic $\kt$-spectrum inside a high energy jet is determined including corrections of relative magnitude $\cO{\sqrt{α_s}}$ with respect to the Modified Leading Logarithmic Approximation (MLLA), in the limiting spectrum approximation (assuming an infrared cut-off $Q_0 =\lqcd$) and beyond ($Q_0\ne\lqcd$). The results in the limiting spectrum approximation are found to be, after normalization, in impressive agreement with measurements by the CDF collaboration. A new integral representation for the "hump-backed" plateau is also reported.
