Study of $D^{*+/-}$ Meson Production in Diffractive $ep$ Scattering at HERA

Abstract

$D^{*+/-}$ production in the diffractive interactions was measured with the ZEUS detector at HERA using integrated luminosities of 44 pb$^{-1}$ in deep inelastic scattering and 38 pb$^{-1}$ in photoproduction processes. Diffractive interactions were identified by a large gap in the rapidity distribution of final states. $D^{*+/-}$ mesons were reconstructed from the decay $D^{*+} -> D^0π_s^+$ with {$D^0 -> K^-π^+$} (+c.c.). Integrated and differential cross sections were compared to theoretical expectations.
