چکیده

We consider the possibility of a direct determination of the polarized gluon density in the proton using charm production with polarized beams at HERA. We study total cross sections and distributions at leading order using different parametrizations of the polarized gluon density. We conclude that charm photoproduction data can be used to constrain the polarized gluon density in the proton if an integrated luminosity of 100 pb will be achieved at HERA. a Work supported by the National Swiss Foundation

TUM/T39-98-21 Exclusive J/ψ photoproduction and gluon polarization †

In exclusive J/ψ production by polarized photons incident on polarized protons , a finite polarization asymmetry arises because of c¯ c Fermi-motion and binding-energy effects. The asymmetry depends on the polarized nonfor-ward gluon distribution of the proton and thus gives information on gluon polarization in the proton. The analyzing power, however, is rather small. Gluon polarization in the...

Prospects for heavy flavour photoproduction at HERA

I discuss few selected topics in heavy flavour photoproduction at HERA which require large integrated luminosity in order to be experimentally investigated. I present phenomenological predictions for bottom production. As a possible application of measurements involving double-tagged charm events, I outline a method for the direct measurement of the gluon density in the proton. The possibility ...

Some recent ZEUS results on the photoproduction of open charm and possible implications for photon structure are discussed. 1 Open Charm Photoproduction at HERA Photoproduction of ‘open’ charm (as opposed to cc̄ bound states) can take place via several processes at HERA. The most obvious is photon-gluon fusion. The photon interacts directly with a gluon from the proton via t-channel charm quark,...
