\midheading{$ZH$ production, processes 101--110}
|
|
\label{subsec:zh}
|
|
|
|
These processes represent the production of a $Z$ boson (or virtual photon)
|
|
in association with a Standard Model Higgs boson that
|
|
decays into a bottom quark pair ({\tt nproc=101-103}),
|
|
or decays into a pair of photons ({\tt nproc=104-105})
|
|
or a pair of $W$ bosons ({\tt nproc=106-108}),
|
|
or a pair of $Z$ bosons ({\tt nproc=109}),
|
|
or a pair of $\tau$'s ({\tt nproc=110}).
|
|
|
|
The $Z$ subsequently decays into
|
|
either an $e^+ e^-$ pair ({\tt nproc=101, 106, 109}), neutrinos ({\tt nproc=102, 107})
|
|
or a bottom quark pair ({\tt nproc=103, 108}).
|
|
The calculation may be performed at NLO, although radiation from the
|
|
bottom quarks in the decay of the Higgs (or the $Z$, for processes
|
|
{\tt 103, 108}) is not included.
|
|
Radiation from the bottom quarks in the decay of the Higgs is included in ({\tt nproc=1010}).
|
|
|
|
When {\tt removebr} is true in processes {\tt 101, 106, 109}, neither the $Z$ boson
|
|
nor the Higgs decays.

NLO calculations can be performed by subtraction, zero-jettiness
|
|
slicing and $q_T$-slicing. NNLO calculations can be performed by
|
|
zero-jettiness slicing and $q_T$-slicing.
