Abstract:

Diffractive production of D^*±(2010) mesons in deep inelastic scattering has been measured with the ZEUS detector at HERA using an integrated luminosity of 44.3 pb^-1. Diffractive charm production is identified by the presence of a large rapidity gap in the final state of events in which a D^*±(2010) meson is reconstructed in the decay channel D^*+ → (D⁰ → K^-π⁺)πs ⁺ (+ charge conjugate). Differential cross sections when compared with theoretical predictions indicate the importance of gluons in such diffractive interactions. © 2002 Elsevier Science B.V. All rights reserved.

Questions on uncertainties in parton distributions

Journal of Physics G: Nuclear and Particle Physics 28:10 (2002) 2717-2722

Authors:

RS Thorne, H Böttcher, AM Cooper-Sarkar, B Reisert, V Shekelyan, WJ Stirling, DR Stump, A Vogt

Abstract:

A discussion is presented of the manner in which uncertainties in parton distributions and related quantities are determined. One of the central problems is the criteria used to judge what variation of the parameters describing a set of partons is acceptable within the context of a global fit. Various ways of addressing this question are outlined.
