چکیده

The ”triple-Regge” analysis of subleading Reggeon contributions to the diffractive structure function in DIS at HERA is presented. The recently published data allow to determine the only free parameter of the analysis related to the ratio of the RRIP and IPIPIP couplings. The large value of this ratio is prefered which is in agreement with analyses of soft hadronic interactions. The role of the subleading Reggeons as well as pions for the fast forward neutron production in diffractive processes is estimated. The forward πN state production is also discussed.

Measurements of the Diffractive Structure Function F D ( 3 ) 2 ( β , Q 2 , x IP ) at HERA

Recent measurements of the diffractive cross section in deep-inelastic scattering (DIS) at HERA are presented. The data are used to investigate the factorisation properties of diffractive DIS and to examine its quantum chromodynamic (QCD) structure. Models based on the colour dipole approach to DIS are also tested. 1. Diffractive Deep Inelastic Scattering At low x in DIS at HERA, approximately ...

STUDY OF D MESON PRODUCTION IN DIFFRACTIVE ep SCATTERING AT HERA

D production in the diffractive interactions was measured with the ZEUS detector at HERA using integrated luminosities of 44 pb in deep inelastic scattering and 38 pb 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 → D0π s with D 0 → Kπ (+c.c.). Integrated and differe...

Diffractive Dijet and Charm Production at Hera

Jet and charm quark production in diffractive interactions is sensitive to the partonic structure of the diffractive exchange. This article reviews recent cross section measurements of such processes in both deep-inelastic scattering (DIS) regime and photoproduction (PHP) from the HERA ep collider experiments. The cross sections are compared to next-to-leading order QCD calculations based on fa...

Diffractive Final States with the H1 Detector at HERA

Abstract. Recent measurements of diffractive dijet and charm quark production in electron-proton collisions using the H1 detector at HERA are presented, where the exchanged photon is either almost real or highly virtual. The data are compared with leading and next-to-leading order QCD calculations based on the diffractive parton distributions obtained from a recent DGLAP QCD analysis of H1 incl...
