A Measurement of the QED Compton Cross Section in Electron-Proton Scattering with the H1 Experiment at HERA Dissertation
A measurement of the double differential leptonic QED Compton cross-section in positron-proton collisions is described. The kinematic range extends in xl from 1.8·10−5 to 1.78·10−3 and in Ql from 1.5 GeV2 to 85 GeV2. The data were accumulated with the H1 detector at the HERA storage ring in 1997, of which about 9.18 pb−1 of the integrated luminosity in that year were included in this analysis. ...

متن کاملDirect Gluon Density Determination in Tagged Charm-photoproduction at Hera
Charm production at HERA is dominated by events with a very small virtuality of the exchanged photon photoproduction In lowest order it proceeds via photon gluon fusion and is therefore directly sensitive to the gluon density in the proton In this thesis single inclusive D spectra in and pt are measured in photopro duction at W p GeV and W p GeV and the energy ow in these charm events is analys...

High pT meson production cross sections for small polar angles with respect to the incident proton direction have been measured in deep inelastic positron proton scattering at low Bjorken x The analysis is based on an integrated luminosity of pb taken with the H detector at HERA in The cross sections are measured as a function of Q as a function of x and as a function of the transverse momentum...
متن کاملStudy of Charm and Beauty Production at HERA/H1 using Dilepton Events
A measurement is presented which investigates the production of charm and beauty quarks in ep collisions at a centre-of-mass energy of 318 GeV. Data taken by the H1 detector at the HERA collider in the years 1999, 2000, 2004 and 2005 are analysed. The collected data correspond to an integrated luminosity of 221.6 pb−1. This is the first measurement of charm and beauty cross sections using HERA ...
