The H1 experiment:

H1 is an international collaboration performing fundamental research in the field of Elementary Particle Physics colliding positron-proton beams of the HERA collider located at the German national laboratory for elementary particle physics DESY (Deutsches Elektronen-Synchrotron) in Hamburg. The main interest of research of the H1 collaboration is the understanding of the proton structure, measuring the proton structure in a wide kinematic range and studying the fundamental interactions between particles with the proton and inside the proton. HERA is also an important tool to search for physics beyond the Standard Model. For more details, refer to the H1 publications.


H1 Collaboration Meeting September 2005
Organized in Belgium

IIHE participating people to H1:

University of Antwerp:

T. Anthonis, E. de Wolf, D. Sunar, T. Sykora, P. Van Mechelen

Contribution of the IIHE to the H1 detector:

The IIHE group has built and installed laready for the first data taking, the COP multiwire proportional chamber of the H1 detector which delivers the vertex position on line.

A new Proton Spectrometer (VFPS) has been constructed and integrated into H1 in 2003. The project is a collaboration of the IIHE, Lund, Hamburg II and Birmingham groups within H1 taking place in the high Luminosity HERA-2000 frame. The new Proton Spectrometer has a large acceptance for tagging the diffractively scattered protons.


Implication of the IIHE physicists in the H1 analyis:

The main activities in the Belgian group have been centered on the study of diffraction: vector meson production, deeply virtual compton scattering, inclusive diffractive photoproduction; and on the study of the characteristics of the hadronic final states.
