Abstract

The W and Q² dependence of the fragmentation functions and of the average multiplicity of charged pions is investigated, using data from the NA9 experiment at the CERN SPS on muon-proton scattering at 280 GeV. A significant increase of pion production with increasing W is observed at fixed Q², leading to a rise of the average charged pion multiplicity, linear in ln W², and of the pion fragmentation function in the central region, i.e. at small |x_F|. This increase can be understood from the kinematic widening of the cms rapidity range proportional to ln W² and the observed W independent height of the rapidity distribution. At fixed W, a rise of the average charged pion multiplicity with Q² is observed. This rise appears to be weaker than that observed for all charged hadrons implying a stronger rise with Q² for kaons and protons.

A significant increase of pion production with increasing W is observed at fixed Q2, leading to a rise of the average charged pion multiplicity, linear in ln W2, and of the pion fragmentation function in the central region, i.e. at small |xF|. This increase can be understood from the kinematic widening of the cms rapidity range proportional to ln W2 and the observed W independent height of the rapidity distribution. At fixed W, a rise of the average charged pion multiplicity with Q2 is observed. This rise appears to be weaker than that observed for all charged hadrons implying a stronger rise with Q2 for kaons and protons.
