A measurement of the gluon density of the proton at hera

Objective



The purpose of the research is the measurement of the gluon density inside the proton. Its knowledge in the new region available at the HERA energy is fundamental for the description of the proton. This is important by itself to understand the interactions inside the proton and also in view of the physics at the next proton-proton collider at CERN, the LHC, where the dominant processes will be described by interacting gluons. The method to carry out the measurement relies on the direct dependence of the heavy quark production on the gluon content of the proton, in the mechanism of photon-gluon fusion, dominant at HERA. In particular the studies of the J/Psi and Open Charm production will allow a statistically very significant determination of the gluon density in the relevant region of invariant fraction of the proton momentum between 5 X 10**-4 and 5 X 10**-1
