The first determination of Generalized Polarizabilities of the proton by a Virtual Compton Scattering experiment

The VCS, A1 collaboration

Absolute differential cross sections for the reaction (e+p -> e+p+gamma) have been measured at a four-momentum transfer with virtuality Q^2=0.33 GeV^2 and polarization ε= 0.62 in t…

Measurement of the K_L -> e+ e- e+ e- Decay Rate

A. Lai

The decay rate of the neutral long-lived K meson into the e+ e- e+ e- final state has been measured with the NA48 detector at the CERN SPS. Using data collected in 1999, a total of…

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…
