Prompt photon production in photoproduction at HERA


Nowak, K; Müller, K (2008). Prompt photon production in photoproduction at HERA. In: Proceedings of the XVI International Workshop on Deep-Inelastic Scattering and Related Topics, London, 7 April 2008 - 11 April 2008.

Abstract

A measurement of prompt photons in photoproduction in ep collisions with the H1 detector is presented. The analysis is based on data taken in the years 2004-2007, corresponding to a total integrated luminosity of 340 pb -1. The photon signal is extracted using a multivariate analysis based on cluster calorimeter shower shape variables. Inclusive and exclusive cross sections are presented as a function of the transverse energy EγT in the range 5 to 15 GeV and the pseudorapidity ηγ range -1.0 to 2.4. The momentum fractions xγ and xproton of the incident photon and proton respectively carried by the constituents participating in the hard scattering process are measured as well. The results are compared to predictions from theoretical calculations.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
