electron proton collision


The experimental method employed is to collide highly energetic protons [920 GeV] with electrons (positrons) [27.6 GeV] which are provided by the HERA accelerator. The particles created in the collision are detected with the H1 Detector

Areas of Research

The characteristics of the particles detected after such a collision provides access to the following areas of current research:

pink dot Structure Functions of the Proton, of the Pion, and of the Diffractive Exchange
pink dot Parton Distributions of Real and Virtual Photons
pink dot Tests of QCD in Jet, Particle, Photon, and Heavy-Quark Production
pink dot Tests of Electro-Weak Theory
pink dot Study of Non-Perturbative Phenomena of Strong Interactions
pink dot Diffractive Scattering and the Mechanism of Colour Neutralization
pink dot Searches for New Particles and New Interactions

HERA II data taking

Since 2003 HERA is in the second phase of its operation which continues until summer 2007. For the first time the lepton beam is polarised.
