Charm photoproduction at low W at HERA — •Gayane Aghuzumtsyan — Physikalisches Institut, Nussallee 12 , 53115 Bonn

Measurements of the production of D^*(2010) mesons in photoproduction at low W using the data collected with the ZEUS detector at HERA between 1998-2000 are presented. Differential distributions of the transverse momentum and pseudorapidity of the charm mesons are presented and compared with theoretical predictions.
