چکیده

Charm quarks are expected to be produced mainly by the photongluon fusion mechanism in γ −N interactions. However, a small part of the total charm cross section originates in similar processes to those appearing in charm hadroproduction through the resolved (hadronic) component of the photon. Although the contribution of the resolved part of the photon is small at fixed target energies, it can help to understand the small but sizeable charge asymmetries measured in charm hadron photoproduction experiments.

Charm-Anticharm Asymmetries in Photoproduction from Perturbative Recombination

The asymmetries between charm and anticharm mesons observed in fixedtarget photoproduction experiments are an order of magnitude larger than the asymmetries predicted by conventional perturbative QCD. We show that these charm meson asymmetries can be explained by a perturbative recombination mechanism for heavy meson production. In this process, a charm quark combines with a light antiquark fro...

Charm-anticharm baryon production asymmetries in photon-nucleon interactions

We report measurements of the charm-anticharm production asymmetries for Λc , Σ c , Σ 0 c , Σ ++∗ c , Σ 0∗ c , and Λ + c (2625) baryons from the Fermilab photoproduction experiment FOCUS (E831). These asymmetries are integrated over the region where the spectrometer has good acceptance. In addition, we have obtained results for the photoproduction asymmetries of the Λc baryons as functions of p...

Recent analyses from Fermilab xed target photoproduction experiment 687 [1] are summarized. Emphasis is placed on strong interaction studies performed on high statistics samples of Charm decays and light quark states. In particular, semi-leptonic measurements of form factors in Cabibbo suppressed modes are described. A Dalitz analysis of the D s ! + + has been performed and can be linked to rec...

Incoherent photoproduction of pions on the deuteron in the first resonance region is investigated with special emphasis on single-spin asymmetries. For the elementary pion production operator an effective Lagrangian model which includes the standard pseudovector Born terms and a resonance contribution from the ∆(1232)-excitation is used. Single-spin asymmetries, both for charged and neutral pio...
