Heavy Flavor Photoproduction in Slac Lattice &cd*
نویسنده
چکیده
We use the SLAC lattice QCD theory to compute the large distance contribution to the process q+p + qH +q, +X, where qH is a heavy quark. In this way, we complete the usual short distance analysis of this process. The relationship between our completion and observation is discussed.

Heavy Flavor Production at Hera
Recent results of open charm and beauty production in electron proton scattering at HERA are presented. In photoproduction, the measured cross sections for charm exceed fixed order NLO QCD calculations. Experimental evidence supports the hypothesis that a significant fraction of photoproduction events with charm can be described by resolved photon processes, where the charm quark is a constitue...
متن کاملNLO Corrections to Heavy Quark Production with Polarized Beams
We present a calculation of the NLO QCD corrections to heavy flavor photoproduction with longitudinally polarized beams. We apply our results to study the spin asymmetry for total charm quark production which will be used for a first direct determination of ∆g by the COMPASS experiment. We also briefly discuss the main theoretical uncertainties inherent in this calculation. Talk presented at th...
متن کاملHeavy Flavor in Photoproduction at HERA
Recent results on charm and beauty photoproduction at HERA are discussed. The perturbative QCD calculations are generally smaller than the measured cross sections, particularly in the forward (proton) direction. The study of charm dijet photoproduction is consistent with a significant contribution of charm excitation processes.

The complete renormalization of the generating functional for Green functions of quark currents between one–baryon states in three flavor heavy baryon chiral perturbation theory is performed to order q3. As an example, we study the kaon loop induced divergences in neutral pion photoproduction off protons. ACCEPTED FOR PUBLICATION IN NUCL. PHYS. B Work supported in part by Deutsche Forschungsgem...
متن کاملHeavy Flavor Fragmentation and Decay at Sld
Results on heavy quark fragmentation obtained using the SLD detector at the SLAC Linear Collider are presented. This talk will cover the ratio of vector to pseudoscalar charmed meson production, the inclusive B hadron energy distribution, the inclusive particle production in heavy jets compared to their production in light jets, and charged and neutral B meson lifetimes.
