Inclusive D-meson and $\Lambda_{c}$ production in two photon collisions at LEP

Mostrar otras versiones (2)

The inclusive production of D/sup *+/, D/sup 0/, D/sup +/ and Lambda /sub c/ is measured by DELPHI in photon photon collisions at LEP-II energies. The measured cross sections are compatible with the QCD calculations having the contributions from the resolved processes sensitive to the gluon density...

Sumario:The inclusive production of D/sup *+/, D/sup 0/, D/sup +/ and Lambda /sub c/ is measured by DELPHI in photon photon collisions at LEP-II energies. The measured cross sections are compatible with the QCD calculations having the contributions from the resolved processes sensitive to the gluon density in photon. The total cross section of the charm quark production in two photon collisions at LEP-II energies is estimated. (28 refs).
