Photoproduction of D* and Jets at H1

Abstract

Photoproduction events containing a charmed meson D±D^{*\pm} and two jets were investigated with the H1 detector using the HERA II data sample. The DD^* meson was reconstructed in the decay channel, D±D0π±Kπ±π±D^{*\pm}\rightarrow D^0\pi^\pm\rightarrow K^\mp\pi^\pm\pi^\pm. Jets were reconstructed using the inclusive ktk_t algorithm and were selected if they have transverse momenta pt(jet)>3.5\gevp_t(\textrm{jet})>3.5\gev. One of the jets was associated with the DD^* meson itself, such that the jet originating from the parent charmed quark as the meson can be tagged. The phase space of the measurement is limited within central rapidity for the DD^* meson and the DjetD^*_\textrm{jet}, η<1.5|\eta|<1.5 while the second jet was measured within, 1.5<η<2.9-1.5<\eta<2.9. Single differential cross sections and double differential distributions were measured and compared to Leading Order Monte Carlo (MC) event generators, \PYTHIA and \CASCADE and with the Next--to--Leading order MC generator \MCATNLO
