Previous: #math617# VTVL/T background
Pairs of vector bosons are also produced in quark fusion processes
giving rise to a spectrum of vector boson pairs with a relatively low
invariant mass. The background is the most serious background to the
H ZZ * Higgs signal in the region below the threshold for a
Higgs decay to two real Z bosons.
A total of 1 000 000 events of vector bosons was simulated with
PYTHIA with a pT cut in the hard scattering of 300 GeV to
study this background.
