Characteristics of leptonic signals forZ boson pairs at hadron colliders

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

We study the production ofZ boson pairs at hadron colliders followed by their subsequent decay into muons or electrons. We take into account the processes\(q\bar q \to ZZ\) andgg →ZZ. The calculation incorporates all effects of the polarization of theZ bosons. Particular emphasis is put on the Higgs-signal where we study the angular distribution of the decay leptons, in order to determine the longitudinal polarisation fraction of theZ bosons. We also study the correlation of the decay planes of the leptons from the twoZ bosons. This correlation may be significant for light Higgs bosons.
