Charm electroproduction at HERA

Abstract

After an introduction to put the analysis in context, chapter 1, the experimental infrastructure is described in chapter 2. The D"* production cross section is measured in a restricted kinematic region as a function of several variables in chapter 3. A comparison of the data with NLO pQCD predictions, which include three light flavours and the gluon as partons in the proton [10], is presented in chapter 4. Also in the same chapter the effects of the fragmentation c#->#D"*"+ are studied. These calculations are used in chapter 5 to extrapolate the data to the full phase space of the D"* meson variables in order to extract F_2"c "a"n"t"i "c.
