The H1 Forward Proton Spectrometer at HERA
The forward proton spectrometer is part of the H1 detector at the HERA collider. Protons with energies above 500 GeV and polar angles below 1 mrad can be detected by this spectrometer. The main detector components are scintillating fiber detectors read out by position-sensitive photo-multipliers. These detectors are housed in so-called Roman Pots which allow them to be moved close to the circul...
متن کاملDiffractive 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...
متن کاملThe Backward Silicon Track Trigger of the HERA Experiment H1
The Backward Silicon Tracker of the H1 experiment is being used in conjunction with a lead-fiber Calorimeter for detailed investigations of inclusive deeply inelastic scattering of leptons from protons, e±P → e±X, and of charm production at small values of the Bjorken variable x, x ≤ 10−3. In this thesis the development of a trigger for the Backward Silicon Tracker is described. The detector wa...
متن کاملDeeply Virtual Compton Scattering at Hera Ii (h1 Results)
New results on the Deeply Virtual Compton Scattering process γ * p → γp (DVCS) from H1 experiment at the ep collider HERA are presented, using data collected during the year 2004 and corresponding to an integrated luminosity of 39.7 pb −1. The DVCS cross section is measured as a function of the photon virtuality, Q 2 , the γ * p c.m.s. energy W and differentially in the momentum transfer square...
متن کاملBeauty in photoproduction at HERA II with the ZEUS detector
The production of beauty quarks in ep collisions should be accurately calculable in perturbative Quantum Chromodynamics (QCD) since the large mass of the b quark provides a hard scale. Therefore it is interesting to compare such predictions to results using photoproduction events where a low-virtuality photon, emitted by the incoming lepton, collides with a parton from the incoming proton. A me...
