The Q^2-dependence of the Generalised Gerasimov-Drell-Hearn Integral for the Proton

A. Airapetian

The dependence on Q^2 (the negative square of the 4-momentum of the exchanged virtual photon) of the generalised Gerasimov-Drell-Hearn integral for the proton has been measured in…

Measurement of elastic electroproduction of phi mesons at HERA

H1 Collaboration, C. Adloff

The elastic electroproduction of phi mesons is studied at HERA with the H1 detector for photon virtualities 1 < Q^2 < 15 GeV^2 and hadronic centre of mass energies 40 < W < 130 GeV…

Search for Compositeness, Leptoquarks and Large Extra Dimensions in eq Contact Interactions at HERA

H1 Collaboration, C. Adloff

The reaction e+p --> e+X is studied with the H1 detector at Hera. The data cover momentum transfers Q^2 between 200 GeV^2 and 30,000 GeV^2 and correspond to an integrated luminosit…

Elastic Photoproduction of J/psi and Upsilon Mesons at HERA

H1 Collaboration, C. Adloff

Cross sections for elastic photoproduction of J/Psi and Upsilon mesons are presented. For J/Psi mesons the dependence on the photon-proton centre-of-mass energy W_gammap is analyse…

Measurement of Di-jet Cross-Sections in Photoproduction and Photon Structure

H1 Collaboration, C. Adloff

The production of hard di-jet events in photoproduction at HERA is dominated by resolved photon processes in which a parton in the photon with momentum fraction x_gamma is scattere…
