Processes ar ZZ-like (eg. four up-type quarks), WW-like (eg. more than two flavours),
or mixed ZZ/WW-like (eg. uudd). Channles that are ZZ-like but could be
WW via off-diagonal elements in the CKM matrix (eg. uuss) are nevertheless
in the ZZ class.
In addition, the processes that have the same electron-lepton flavour
as the initial state are singled out as sigle W or single Z (or mixes).
For single Z, one also seperates between e+e- and nu_e nu_e final states.
Of course, these chanels also contain WW and ZZ diagrams, with one of the
X:s going to ee (or W going to enu) in the opposite beam-polarisation
configurations. However, the single-boson contribution is typically larger.
Also note that the sigleZee channel contains the multi-periferal
gamma gamma diagrams. However, there are default generator-level cuts
in Whizard that suppress their contribution. Instead, the deicated gamma gamma
samples should be used.
Finally, also note that there is a default cut on the invariant mass of any e+e--pair
(M_ee>4 GeV) in the final state. Therefore, in the singleZ-leptonic and signleZsingleWMix-leptonic
there are also complementary samples for ee->ee nu nu with the cut reversed (ie. M_ee<4 GeV).
Any analysis sensitive to Missing Energy + a low mass lepton pair must include these samples
as well. Note that there is no default cut on M_mumu or M_tautau, only on M_ee.
