One-loop contributions of charginos and neutralinos to W+ W- production in e+ e- collisions
Kaoru Hagiwara, Shinya Kanemura, Yoshiaki Umeda
We study one-loop effects of charginos and neutralinos on the helicity amplitudes for the process in the MSSM. The calculation is tested by using two methods. Fi…
Factorization Breaking in Diffractive Photoproduction of Dijets
M. Klasen, G. Kramer
We have calculated the diffractive dijet cross section in low-Q^2 ep scattering in the HERA regime. The results of the calculation in LO and NLO are compared to recent experimental…
Heavy Quarkonium Production with Polarized Hadrons and Photons
M. Klasen, B. A. Kniehl
We investigate the inclusive production of prompt J/psi mesons in polarized hadron-hadron and photon-hadron collisions in the factorization formalism of NRQCD. Numerical results ar…
J/ψProduction in Direct and Resolved Photon Collisions
Michael Klasen
The production of J/Psi mesons in photon photon collisions allows for a test of factorization in color-octet processes as predicted by NRQCD and observed at the Tevatron. We calcul…
Gluino Pair Production in e^+e^- and Photon-Photon Collisions at CERN CLIC
S. Berge, M. Klasen
We confront the generally small cross sections for gluino pair production in e^+e^- annihilation with the much larger ones in photon-photon scattering at a multi-TeV linear collide…
The Production of Gluino Pairs in High Energy e+ e- Collisions
Stefan Berge, Michael Klasen
In the Minimal Supersymmetric Standard Model (MSSM), the process e+ e- -> gluino gluino is mediated by quark/squark loops, dominantly of the third generation, where the mixing of l…
