Description
Similarly as in lepton-hadron scattering, but less pronounced than in e+e- annihilation at comparable energies, we observe a rise of the ''sea-gull'' wings with CMS energy. The large average transverse momenta around Feynman vertical strokexFvertical stroke = 0.4 are mainly due to high multiplicity events, for which also a tail develops in the multiplicity distribution. Neither of these effects can be reproduced by currently used low-pT fragmentation models. (orig.)
