#### 95.1 WH production, processes 91-100, 900

This process can be calculated at LO, NLO, and NNLO. These processes represent
the production of a W boson which subsequently decays leptonically, in association
with a Standard Model Higgs boson that decays into a tau pair (nproc=91, 96),
decays into a b-quark pair (nproc=92, 97), a pair of photons (nproc=93, 98), or a
pair of W-bosons (nproc=94, 99), a pair of Z bosons (nproc=95, 100).
Note that in the cases of Higgs decay to W,(Z) pairs, below the W,(Z) pair
threshold one of the W,(Z) bosons is virtual and therefore one must set
zerowidth=.false.. The calculation may be performed at NNLO for these
processes.

Radiation from the bottom quarks in the decay, an NLO effect, is included in
(nproc=920, 970). nproc=900 may be used to compute the sum over both W
charges in one run (with the decay products 3 and 4 representing lepton and
antilepton respectively). This sum is performed by adjustng the CKM matrix to
allow both charges of the W boson.

When removebr is .true., neither the W boson nor the Higgs decays.

For more information on this process see refs. [1, 2, 3]. 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.
