Charm spectroscopy and exotics at ZEUS
Leonid Gladilin
Light and charmed hadrons are produced copiously in ep collisions with a centre-of-mass energy of 318 GeV at HERA. Results of the ZEUS Collaboration on pentaquark searches, deutero…
Charm dijet angular distributions in gamma-p collisions with ZEUS at HERA
Leonid Gladilin
Dijet angular distributions of photoproduction events in which a D*+/- meson is produced in association with one of two energetic jets have been measured using an integrated lumino…
Heavy Flavor in Photoproduction at HERA
L. Gladilin
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…
Charm Hadron Production Fractions
L. Gladilin
The world average values for the probabilities that a charm quark fragments into D^*+ and Ds^+ have been calculated to be f(c->D^*+)=0.235+/-0.007(+/-0.007) and f(c->Ds^+)=0.101+/-…
