AbstractAbstract
[en] Photoproduction events containing a charmed meson D*± and two jets are investigated with the H1 detector using the HERA II data sample. The measurement is based on e+p collisions during the period of 2006/2007 data taking and uses integrated luminosity of 113.14 pb-1. The kinematic range of the measurement covers 100 GeV< Wγp<285 GeV for photon virtuality of Q2<2 GeV2. The D* mesons are reconstructed in the decay channel, D*±→D0π±→K-+π±π±. Jets were reconstructed using the inclusive kt algorithm and are selected if they have transverse momenta of pt(jet)>3.5 GeV. One of the jets has to be associated with the D* meson itself, such that the parent charmed quark can be tagged. The phase space of the measurement is limited within the central rapidity for the D* meson and the D*jet, vertical stroke η vertical stroke <1.5 while the second jet was measured within, -1.5<η<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 MC rate at NLO.
