Define the model:

{{{
model = SM
}}}

This is the CC10 charged current process important
for LEP physics. No flavor summation for jets here.

{{{
process cc10 = e1, E1 => e2, N2, u, D
}}}

Compilation (optional):

{{{
compile
}}}

We set the muon mass to zero.

{{{
mmu = 0
}}}

The final LEP energy:

{{{
sqrts = 209 GeV
}}}

Integrate the process:

{{{
integrate (cc10) { iterations = 12:20000 }
}}}

We set a luminosity of 10 inverse femtobarn

{{{
luminosity = 10 
}}}

Define title etc. as global variables, that will be used by PLOT

{{{
$description =
  "A WHIZARD 2.0 Example.
   Charged current CC10 process from LEP 2."
$ylabel = "$N_{\textrm{events}}$"
}}}

Allocate plots and set up the analysis:

{{{
$title = "Di-jet invariant mass $M_{jj}$ in $e^+e^- \to \mu^- \bar\nu_\mu u \bar d$"
$xlabel = "$M_{jj}$/GeV"
histogram m_jets (70 GeV, 90 GeV, 0.5 GeV)

$title = "Muon energy $E_\mu$ in $e^+e^- \to \mu^- \bar\nu_\mu u \bar d$"
$xlabel = "$E_\mu$/GeV"
histogram e_muon (0 GeV, 209 GeV, 4)

analysis = record m_jets (eval M [u,D]);
           record e_muon (eval E [e2])
}}}

Simulate and write out the analysis:

{{{
simulate (cc10) 

$analysis_filename = "cc10"
write_analysis
}}}
