Diquark production inep collisions

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

We examine the production of single diquarks (D) and diquark pairs\((D\bar D)\) inep collisions using the effective photon approximation. Cross-sections for both mechanisms are found to be quite sensitive to the assumed charged of the diquark but can lead to significant production rates in all cases at HERA and futureep colliders. Backgrounds from QCD jet production are found to be potentially significant in the case of singleD production where the signal to background is approximately one-to-one whereas the production of\(D\bar D\) pairs is relatively back-ground free.
